TDK Corporation has announced the addition of eight high-voltage models to the TDK-Lambda Genesys 3U Series of AC/DC programmable power supplies. These include 800, 1000, 1250 and 1500 V models with output power levels of 10 and 15 kW. These high-voltage models address the requirements for applications in the industrial, automotive, alternative energy, oil and gas, lighting and semiconductor markets.

These units can operate in either constant-voltage (CV) or constant-current (CC) mode and can accept a three-phase AC input of either 400 or 480 VAC (with standard passive power factor correction).

Safety features included are safe/auto restart, last-setting memory and built-in protective functions. With safe start configured, the power supply returns to its last operation settings after a power interruption but with the output disabled, while with auto restart, the power supply returns to the last used operation settings after a power interruption. Built-in protective functions include overvoltage protection (OVP), undervoltage limit (UVL), foldback protection (FOLD) and overtemperature protection (OTP).

Higher power systems can be configured using the master/slave ‘Advanced’ parallel operating mode (utilising two-wire current share). This mode configures the Master unit to be the single point for programming, measurement and status of the total current of the paralleled system. Four units can operate as a single 40 or 60 kW power supply.

Using the embedded 16-bit RS232/RS485 multidrop digital communication interface, up to 31 power supplies may be controlled in an addressed RS485 daisy-chain configuration.
