Lambda / TDK / EMI LPD422A

The Lambda / TDK / EMI LPD422A-FM is a dual-output regulated DC power supply engineered for laboratory, industrial, and commercial applications. It delivers two independent, continuously variable DC outputs spanning 0 to 40 VDC at up to 1 A per channel, with exceptional line and load regulation of 0.01% + 1 mV. The unit operates in constant voltage/constant current mode with continuously adjustable current limiting, short-circuit protection, and automatic safeguards against overvoltage and overtemperature faults.

Front-panel analog meters provide simultaneous voltage and current monitoring for each output. Remote sensing and programming terminals enable precision applications requiring external feedback control. Convection cooling eliminates fan noise and maintenance concerns in sensitive measurement environments.
