With the maximum output power of 217 W, the GPP-Series, the multi-channel programmable DC power supply, includes four models: GPP-1326 (0 V to 32 V/0 A to 6 A) for single-channel output and GPP-2323 for dual-channel output (CH1:0 V to 32 V/0 A to 3 A, CH2: 0 V to 32 V/0 A to 3 A), GPP-3323 for three-channel output (CH1: 0 V to 32 V/0 A to 3 A, CH2:0 V to 32 V/0 A to 3 A, CH3: 1.8 V, 2.5 V, 3.3 V, 5.0 V/5 A) and GPP-4323 for four-channel output (CH1:0 V to 32 V/0 A to 3 A, CH2:0 V to 32 V/0 A to 3 A, CH3:0 V to 5 V/0 A to 1 A, CH4: 0 V to 15 V/0 A to 1 A).

 

This series not only provides high program resolution (1 mV/0.1 mA) and read back resolution (0.1 mV/0.1 mA), but also features optimal low-ripple noise characteristics ≦350 µVrms/≦2 mArms and output transient recovery capability≦50 µs (or 100 µs). Independent output on-off switch is provided for each channel.
