GW Instek PPH-1506D High Precision Dual Channel Output DC Power Supply (CH1:0~15V/0~3A or 0~9V/0~5A;CH2:0~12V/0~3A)

The GW Instek PPH-1506D is another member of the programmable high-precision DC power supply family. Let’s explore its features and specifications:

Dual Channel Output:
- Channel 1: Voltage range of 0~15V (or 0~9V) and current range of 0~3A (or 0~5A).
- Channel 2: Voltage range of 0~12V and current range of 0~3A.
- The PPH-1506D is designed to handle various measurement scenarios.
Display and Measurement:
- 3.5-inch TFT LCD display for clear visualization.
- Includes a built-in digital voltmeter (DVM) measurement function.
- High measurement resolution: 1mV/0.1μA for the 5mA range.
Fast Transient Recovery Time:
- Unlike conventional power supplies, the PPH-1506D boasts an impressive transient recovery time.
- Within 40μs, it can recover the output voltage to within 100mV of the previous voltage output when the current level changes from 10% to 100% of the full scale.
- Rise time: 0.2ms, fall time: 0.3ms (100 times faster than typical power supplies).
Pulse Current Measurement:
- The internal high-speed sampling circuit allows pulse current measurement without requiring a current probe and oscilloscope.
- Current read-back accuracy: 0.2% + 1μA (at 5mA range), with a read-back resolution of 0.1μA.
Battery Simulation Function:
- PPH-1506D can simulate battery behavior during discharge.
- It compensates for voltage drops caused by pulse currents, making it suitable for applications like cellular phones, wireless devices, and wearables.
Safety and Connectivity:
- Includes OVP (Over Voltage Protection), OCP (Over Current Protection), and OTP (Over Temperature Protection) features.
- Offers USB (Device & Host), GPIB, and LAN interfaces for connectivity.
- Supports external relay control.

In summary, the GW Instek PPH-1506D is a reliable and precise dual-channel DC power supply, ideal for engineers and researchers working on a wide range of electronic projects.
