GW Instek PPH-1503D High Precision Dual Channel Output DC Power Supply

Overview

The GW Instek PPH-1503D is a programmable dual-channel DC power supply designed for precision measurement and testing applications. Channel 1 provides 45W of power (0-15V/0-3A or 0-9V/0-5A) with exceptional transient response, while Channel 2 provides 18W (0-12V/0-1.5A). The unit features a 3.5-inch TFT LCD display and built-in digital voltmeter for direct voltage measurement on devices under test.
