The GW Instek PPH-1503 is a high-speed and high-precision DC
Power Supply with dual range of 15V/3A or 9V/5A. PPH-1503 is exclusively designed to meet low power consumption
requirements and users’ great demands of accuracy, speed and resolution of both voltage and current. Circuits
are designed with swift response capability to provide a stable voltage output while experiencing load changes.
PPH-1503 is designed to simulate battery response when a significant
voltage drop occurs. Recovery time of 40 us or less is guaranteed when the maximum voltage drop is within 100mV.
Moreover, when users change the voltage level and conventional power supply does not have sufficient speed to
reach the set level, PPH-1503 provides rise time of 0.15ms and fall time of 0.65ms, which are hundredstimes
faster than that of the conventional power supplies.
Users can remotely control PPH-1503 via a PC by using USB, GPIB and
LAN interfaces which are standardly equipped. PC software can be downloaded from GW lnstek website. These unique
features make PPH-1503 an ideal power source for production lines, R&D laboratories, device inspection, maintenance
centers or facilities with the requirements of a swift and precise power supply with DVM .
