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.
