GW Instek PEL-3041H Programmable Electronic Load

Overview

The GW Instek PEL-3041H is a single-channel programmable DC electronic load from the PEL-3000H series, providing 350W capacity (up to 800V, 17.5A) with 0.84A/µs current Slew Rate. This high-voltage variant is specifically designed for testing EV and HEV in-vehicle chargers, DC/DC converters, high-voltage battery systems, and other demanding high-voltage applications requiring stable power sink capabilities.

Building on the PEL-3000 series foundation, the PEL-3041H offers three current ranges across all models in the PEL-3000H series and includes voltage monitor BNC terminals on the front panel. It supports seven operating modes, sequence functions, and dynamic load simulation with comprehensive protection features suitable for critical high-voltage testing scenarios.
