PPH-1500 Series

The GW Instek PPH-1500 Series is a programmable high-precision DC power supply featuring a high-speed transient response time of less than 40 microseconds using the front output (less than 80 microseconds from the rear output) within a 20 mV recovery window. A 3.5-inch TFT LCD provides clear visualization of output parameters and operating status. These characteristics make the PPH-1500 ideal for powering fast-switching digital circuits, FPGAs, and mixed-signal designs where supply voltage stability during rapid load changes is critical.

Transient Response (Rear)	< 80 us (within 20 mV)
Display	3.5-inch TFT LCD
Relay Control	External on/off
Output Terminals	Front and rear panel
Key Lock	Function available
Preset Memory	5 sets (including output on/off states)
Protection	OVP, OCP, OTP
Interface	USB, GPIB, LAN (all standard)

Five preset memory sets, including stored power output on/off states, enable rapid switching between test configurations for multi-product production lines or multi-stage R&D workflows. External relay on/off control supports integration with test fixtures and automated handlers where power sequencing must be coordinated with mechanical or signal-switching operations. The key lock function prevents accidental parameter changes during unattended test runs.

The dual-channel PPH-1506D and PPH-1510D models provide independent outputs for powering multi-rail designs from a single instrument, reducing bench space and simplifying cabling. Standard USB, GPIB, and LAN interfaces on all models enable remote control and integration into automated test systems without optional adapters.
