Amrel LPS-302

The Amrel LPS-302 is a 60 W linear programmable DC power supply built for electronic testing, development, and production environments. It delivers adjustable voltage and current outputs across dual ranges with exceptional stability—1 mVrms noise and 10 mVp-p ripple (20 Hz–2 MHz) ensure clean power for sensitive circuits. The unit combines precision voltage control (±0.2% accuracy, 10 mV resolution) with stable current regulation (±0.5% accuracy, 1 mA resolution) and supports both local front-panel operation and remote RS-232C command via ASCII protocol at 2400 baud.
