GW Instek PEL3031E Programmable Electronic Load

Overview

The GW Instek PEL3031E is a programmable single-channel electronic load designed for testing components, batteries, portable chargers, and power products requiring low to medium power consumption. This unit provides both static and dynamic load operation with flexible test modes and comprehensive automation features for component characterization and device validation.

Key Features

• Seven operating modes: CC (constant current), CV (constant voltage), CR (constant resistance), CP (constant power), plus combined modes (CC+CV, CR+CV, CP+CV)
• Static, Dynamic, and Sequence functions (Normal and Fast) for complex test patterns
• Fast Sequence with 25µs time resolution for simulating real-world load conditions
• Soft Start function to control current rise time and prevent transient voltage drops and inrush current
• Battery discharge automation with flexible stop settings and adjustable slew rates
• OCP and OPP test automation for verifying device protection points
• Max slew rate: 2.5A/µs
• Comprehensive protection: OVP, OCP, OPP, OTP, RVP, UVP
• Remote Sense capability for accurate measurement at DUT terminals
• External voltage and resistance control via analog terminal
• Easy-to-read LCD panel with user-friendly interface

Applications

• Electronic component testing and characterization
• Battery discharge testing and capacity validation
• Power supply testing (chargers, adapters, regulated supplies)
• Portable power charger evaluation
