GW Instek PPH-1503 Programmable High Precision Linear DC Power Supply

GwInstek_logo_index

The GW Instek PPH1503 is a high-speed and high-precision DC Power Supply with dual range of 15V/3A or 9V/5A. The PPh-1503 is exclusively designed to meet low power consumption requirements and users’ 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. For example, when switching cellular phone from standby to talk mode, the current consumption will be dramatically changed within milliseconds. When load current exceeded current limit, two operational modes: Limit and Trip can be selected. Under limit mode, PPH-1503 will automatically switch to constant current (CC) mode. Under Trip mode, voltage output will automatically turn off.

The GW Instek PPH-1503 Programmable High Precision Linear DC Power Supply is designed to provide fast response to the current change for recovering the output voltage at a minimum variation. The high sampling rate allows fast feedback in voltage and current measurement to expedite products’ testing speed, which is able to increase the test throughout production. Sink function can be used to test the battery charger of portable devices.

The high precision performance of PPH-1503 provides the measurement capability in low power consumption level. One built-in DVM (Digital Volt-Meter) with input ports is designed to measure any point on Device Under Test (DUT)while PPH1503 is outputting voltage and current. Besides, two ports are located on the front and rear panel which users can only select one to perform tests based upon their connection convenience.

The GW Instek PPH-1503 is and 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.
