TDK Corporation announces the addition of eight new High Voltage models to the TDK-Lambda Genesys 3U AC/DC Programmable Power Supply Series. Added models include 800V, 1000V, 1250V and 1500V with Output power levels of 10kW and 15kW. These High Voltage models address the requirements for applications in the Industrial, Automotive, Alternative Energy, Oil & Gas, Lighting and Semiconductor markets.

Carrying a five-year warranty, the TDK-Lambda Genesys™ High Voltage models have the same front panel features and compact dimensions (3U (133mm) high and 19” (483mm) wide) as the standard 10kW/15kW models (7.5V to 600V). These units can operate in either Constant-Voltage (CV) or Constant-Current (CC) mode and can accept a three-phase AC input of either 400VAC or 480VAC (with standard passive Power Factor Correction).

New High Voltage model features include a wider AC Input voltage range for 400VAC input (342VAC – 440VAC), higher efficiency (> 93%), faster Up/Down-Programming Response Time (17ms/20ms), Output isolation up to 1500V, built-in Isolated J1 Remote Analog 5V/10V Program/Monitor, Two-Wire Parallel current share (for parallel system operation), cooling fan speed control for reduced audible noise and extended fan life and lighter weight (< 70lbs).

As with all of the TDK-Lambda Genesys programmable power supplies, several safety and advanced system configuration features are included.

Safety features included are Safe/Auto Re-Start, 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 Re-Start, the power supply returns to the last used operation settings after a power interruption. Last Setting Memory retains settings such as the Output voltage/current, Output ON/OFF, OVP/UVL level, Foldback and Start-Up mode at each AC Input turn-off sequence. Built-in protective functions include Over- Voltage Protection (OVP), Under-Voltage-Limit (UVL), FOLDback protection (FOLD) and Over-Temperature Protection (OTP).

Higher power systems can be configured using the Master/Slave “Advanced” Parallel operating mode (utilizing 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. Thus, four units can operate as a single 40kW or 60kW power supply, increasing the flexibility for system designers.

Common to the entire TDK-Lambda Genesys™ family is the embedded 16-bit RS-232/RS-485 Multi-Drop Digital communication interface. Using this Digital communication interface, up to 31 power supplies may be controlled in an addressed RS-485 daisy-chain configuration.
Other optional Digital and Analog communication interfaces include the LXI Class C compliant LAN and the IEEE (488.2 and SCPI-compliant) Multi-Drop Digital communication interfaces (which include a selection of instrument drivers such as NI LabVIEW and NI LabWindows™) as well as a 4-20mA Isolated Analog programming/monitor interface.

CE marked in accordance with the Low Voltage Directive, the TDK-Lambda Genesys 3U 10kW/15kW Power Supply Series conforms to conducted and radiated EMI in accordance with EN55011A and FCC Part 15J-A.

Safety agency approvals include UL60950-1 and EN60950-1.
