Chroma 63103A Programmable DC Electronic Load

Overview

The Chroma 63103A is a single-channel programmable DC electronic load designed for comprehensive power supply testing. With 60A, 80V, and 300W maximum capacity, it excels at low-voltage power supply applications and can sink 60A even at voltages as low as 1V, making it ideal for modern low-voltage DC systems.

Key Features

• High current capability: 60A maximum at voltages from 0V to 80V
• Supports operation down to zero volts at reduced current levels
• Multiple operation modes: constant current (CC), constant resistance (CR), constant power (CP), and constant voltage (CV)
• Dynamic loading with speeds up to 20kHz
• Fast slew rate: 0.32mA/s to 10A/s response time
• 16-bit precision voltage and current measurement with dual-range
• Remote sensing for accurate measurements without voltage drop errors
• Over-current protection (OCP) testing and automatic detection
• Programmable sequences: up to 100 stored configurations in EEPROM
• Digital I/O control for automated testing integration
• Comprehensive protection: OV, OC, OP, OT, and reverse polarity protection
• Interfaces: USB, GPIB, and RS-232 (mainframe dependent)

Applications

• Low-voltage power supply testing and validation (3.3V, 5V systems)
• Load transient response simulation
• Automated test sequences with programmable configurations
• OCP circuit validation and design verification
• Battery and supercapacitor discharge testing with timing functions
• Parallel configuration for increased power testing
