The Amrel PPS18-4D is a dual-channel programmable DC power supply engineered for precision power delivery in test, measurement, and development environments. Each channel delivers 0–18V at 0–4A with exceptional line and load regulation (0.001% + 1mV for voltage; 0.1mA for current). Remote sensing capability accommodates up to 0.5V drops across load leads. The instrument includes programmable overvoltage and overcurrent protection, reverse polarity protection, and output enable/disable control. Temperature stability is maintained across 0°C to 50°C operation with voltage coefficient of 100ppm/°C and current coefficient of 200ppm/°C. Noise performance reaches 1mV RMS/PK-PK for voltage and 0.1mA RMS/PK-PK for current across 20Hz–20MHz.
