TDK Lambda GEN40-85 Programmable DC Power Supply
The TDK Lambda GEN40-85 Programmable DC Power Supply achieves a typical efficiency of 86%. The voltage ripple noise is limited to 0.008 Vrms across 5 Hz to 1 MHz. The current ripple noise remains below 0.2 Arms within the same frequency band. These low noise levels suit precision automation testing environments. The model includes RS-232 and RS-485 interfaces as standard features. Additional interface options include LAN with LXI compliance for network control. The USB and GPIB interfaces are also available as options. These interfaces enable remote monitoring and control of the power supply.
The output voltage of the power supply can be adjusted from 0 to 40 Vdc. The output current can similarly be adjusted from 0 to 85 A. This wide adjustment range supports varied load testing requirements. The model accepts an input frequency range of 47 to 63 Hz. The GEN40-85 measures 423 mm in width and 88 mm in height. The depth of the unit is 442.5 mm with a typical weight of 13 kg. This compact 2U form factor suits rack mounted automation systems. The design allows zero stacking through dedicated air intake.
The GEN40-85 programmable DC power supply is designed for industrial automation applications. It delivers a rated output voltage of 40 Vdc and a rated output current of 85 A. This configuration allows it to supply a rated output power of 3400 W. The unit operates from an AC input voltage range of 170 to 265 Vac. The pushbuttons on the model allow coarse and fine adjustment of voltage and current. The operators can configure parallel master or slave mode using these controls. The unit supports auto restart and safe start modes for flexible operation.
The front panel of the DC Power Supply includes reliable encoders for output voltage and current control. These encoders also set OVP and UVL limits directly. The volt display shows output voltage along with address and baud rate settings. The current display indicates output current and total current during parallel operation. The GEN40-85 has been tested to MIL-810F method for vibration resistance. The shock resistance is rated below 20 G using half sine pulses of 11 milliseconds.
