With the maximum output power of 217W, the GPP-Series, the multi-channel programmable DC power supply, includes four models:

  1. GPP-1326 (0~32V/0~6A) for single-channel output and
  2. GPP-2323 for dual-channel output (CH1:0~32V/0~3A, CH2: 0~32V/0~3A),
  3. GPP-3323 for three-channel output (CH1: 0~32V/0~3A, CH2:0~32V/0~3A, CH3: 1.8V, 2.5V, 3.3V, 5.0V/5A) and
  4. GPP-4323 for four-channel output (CH1:0~32V/0~3A, CH2:0~32V/0~3A, CH3:0~5V/0 ~1A, CH4: 0~15V/0~1A).


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


GPIB and/or LAN are optional, please inquire for pricing.
