GW Instek GPP-1205 Single-Channel Programmable DC Power Supply, 0-20V, 0-5A, 100W, USB/LAN, CE 01PP120520GS

Precision electronics work demands a power source that delivers exact voltage and current without drift or noise. The GW Instek GPP-1205 is a single-channel programmable DC power supply that provides 0–20 V and 0–5 A with 100 W maximum output, giving you the control needed for circuit development, testing, and production. Its 1 mV and 1 mA resolution lets you set values with confidence, while the 4.3-inch TFT LCD shows all parameters clearly.

Who is it for

Engineers, technicians, and educators who need a reliable benchtop supply for prototyping, QA, or lab experiments. The GPP-1205 suits anyone who requires programmability and remote control via USB or LAN, and who values stable, low-ripple output for sensitive components.

Tips

Use the LAN interface to integrate the GPP-1205 into automated test systems or to control it remotely from a PC. The remote sensing feature compensates for voltage drop in long leads, ensuring your circuit receives the exact voltage you set. For sensitive analog designs, the low ripple and noise specifications help maintain signal integrity.
