Phase Connections
The phase connection option enables parallel connection of phases to double the rated current for single-phase or split-phase in voltage controlled operation. Supported phase connections are as follows:
- 3L AC/DC:
Rated current: 1- to 3-phase - 2L AC/DC (double voltage/double current)
Double rated current: L1 to L2 and L3 to N connected in parallel
Double rated voltage: Inverted curve from L1 and L2 to L3 and N - 1L AC/DC (double current)
Double rated current: L1 to L2 and L3 to N connected in parallel - 1L DC (triple current)
Triple rated DC current: L1, L2 and L3 connected in parallel
The phase connections can be configured via ACSControl, the application programming interface (API) or the optional TC.ACS.CANmp interface. This option is included in the full waveform generator CV. The phase connections can also be used together with the basic waveform generator CV, the P-HIL power amplifier, etc. and are also available as a stand-alone option if the functionality of the full waveform generator CV is not required.

Grid Impedance Simulation
In addition to the basic or full waveform generator, the grid impedance option provides simulation of the behavior of a real AC grid. This tool eliminates the need to use real power resistors and coils to simulate grid impedance and can replace expensive and bulky solutions, especially at higher power levels. The grid impedance simulation option is therefore a valuable tool for analyzing the influence of a real AC grid on a test object.
If a sense measurement is not possible or it is used for other purposes, this option also offers the possibility of compensating the grid impedance. The grid impedance can be configured via ACSControl, the application programming interface (API) or the optional TC.ACS.CANmp interface.

Standards IEC/EN 61000-3-X and IEC/EN 61000-4-X for EMC Emission and Immunity Testing
REGATRON offers full and pre-compliance EMC test systems. In addition to the TC.ACS AC power supply unit and the EMC test suite with one or both standards packages IEC/EN 61000-3-X and IEC/EN 61000-4-X the flicker impedance network TC.FLK, the voltage slope enhancer TC.VSE and the power analyzer LMG671 are included, depending on the EMC test system selected.
Current Control Mode
The current control mode option enables to operate the TC.ACS AC power supply current controlled. In combination with the fast analog interface, the TC.ACS device can be used as a highly dynamic current-controlled power amplifier for P-HIL applications.
The current control mode option also includes the basic waveform generator CC. Activated synchronization enables the generation of simple sinusoidal current curves to simulate a 3-phase AC load at one operating point. Deactivated synchronization allows the simulation of a 3-phase AC current source. Each phase is controlled against the neutral line. For this reason, the neutral conductor must be connected to ensure fault-free operation.
The current control mode can be configured and controlled via ACSControl, the application programming interface (API) or the optional TC.ACS.CANmp interface.
Order Code: Current Control Mode
Full Waveform Generator CC
The full waveform generator CC (FWG CC) option unlocks the full functionality of the TC.ACS current controller and enables simulation of various 1- to 3-phase AC loads at different operating points when synchronization is activated. Deactivated synchronization allows the simulation of a 1- to 3-phase AC current source. The FWG CC option enables the creation of longer and more complex test sequences. It includes also the current control mode option. Each phase is controlled against the neutral line. For this reason, the neutral conductor must be connected to ensure fault-free operation.

RLC Load Mode
The RLC load mode option enables to simulate various 1- to 3-phase AC loads in one operating point by setting the specific value of resistance (R), inductance (L), and capacitance (C). By measuring the voltage at the output, the TC.ACS device calculates and regulates the reference current based on the specified R, L and C values. Consequently, the desired AC load is simulated. Due to the choice of 12 different topologies, a wide range of AC load behaviors can be simulated.
Each phase is controlled against the neutral line. For this reason, the neutral conductor must be connected to ensure fault-free operation.
The RLC load mode can be configured and controlled via ACSControl or the application programming interface (API).
Order Code: RLC Load Mode
Power Mode
The Power Mode option enables accurate control of output power by continuously adjusting voltage or current to match a defined reference. It works in both source and sink modes, synchronizing to the sinusoidal voltage at the output or analog inputs via the interface X609.
A constant power for each phase can be set with the basic power mode. This mode can be configured using the setpoint pairs ‘apparent power (S)’ and ‘power factor (cos(φ))’, ‘active power (P)’ and ‘reactive power (Q)’, or ‘apparent power (S)’ and ‘phase angle (φ)’. A preview shows the configured power as a pointer diagram.
The full power mode enables to simulate load profiles. Dynamic sequences of up to 100 steps per phase allows complex time-dependent power control. The steps can be configured using the setpoint pairs ‘apparent power (S)’ and ‘phase angle (φ)’ or ‘active power (P)’ and ‘reactive power (Q)’. A preview of the load profile makes the configuration easy and user-friendly.
Each phase is controlled against the neutral line. For this reason, the neutral conductor must be connected to ensure fault-free operation.
The power mode can be configured and controlled via ACSControl, the application programming interface (API) or the optional TC.ACS.CANmp interface.

Analog I/O Interface X609 Adapter
The analog I/O interface X609 adapter is designed to provide easier access to the X609 interface located on the rear of the TC.ACS device, replacing the original M12 flush-type connector with more user-friendly BNC connectors.
The adapter connects to X609 via its X630 interface and additionally exposes:
- A mirrored X609 interface for direct passthrough
- Convenient BNC connectors for 4 analog ouputs
- A multi-pin connector with individual access to the 4 analog input signals, which are usable as analog interface X609 for power amplifier
As a result, the X609 adapter enables faster and more efficient testing, development and integration.

CAN Interface TC.ACS.CANmp
The TC.ACS.CANmp interface (X652/X653) enables fast and flexible communication between TC.ACS devices and external systems via a standard CAN bus, compliant with ISO 11898-1 (CAN 2.0B, Layers 1 and 2). Thanks to the user configurable CAN multi-protocol (CANmp) the creation of a new CAN network or the integration into an existing one is easily done.
It supports a 1 kHz data rate with a maximum resolution of 32-bit per signal and is configurable via ACSControl, including intuitive dbc file handling. In addition, the 8 digital inputs and outputs enable the implementation of automatic switching between two CAN masters, complete system reconfiguration or seamless integration into dynamic or modular test setups.
Key Features:

- Up to 20 transmit and 20 receive signals (16-bit) at 1 kHz
- Cyclic or synchronized messaging with prioritization options
- 8 digital inputs and 8 digital outputs (X654) for logic control and operating state indication, fully configurable via ACSControl

- 4 integrated relays enable potential free contacts
Order Code: TC.ACS.DIG8IOST
Sense Board
The sense board enables direct voltage measurement at the device under test (DUT), allowing for significantly improved voltage control. This setup compensates for voltage drops across load cables or transformers and ensures greater accuracy and performance in a TC.ACS system.
There are three voltage rating options to meet a range of application requirements:
- 500 Vpeak (L-N)
- 750 Vpeak (L-N)
- 1500 Vpeak (L-N) / 1500 Vpeak (L-L)
Note: Together with the sense board only the analog I/O interface X609 for P-HIL power amplifier is supported.
Order Code: TC.ACSUSense (500 V / 750 V / 1500 V)
XCD Option and XCDBox for AC Filter Discharge
Discharging of the AC filter is mandatory when using the device with a plug connection. The device internal option XCD ensures a discharge time of the AC filter less than 1 s as required by EN 62477-1.
The XCDBox is developed for cases where this option needs to be retrofitted to a TC.ACS system that has already been delivered, e.g. because a plug has been fitted. The XCDBox can simply be mounted on a top-hat rail and connected to the input of the TC.ACS device. This means that the option does not need to be retrofitted at the factory.
