Chroma 63112A Programmable DC Electronic Load

Overview

The Chroma 63112A is a high-power programmable DC electronic load module capable of sinking up to 240A at 80V with a maximum power rating of 1200W. This load module combines flexible operation modes with advanced dynamic loading capabilities, making it suitable for testing power supplies, DC/DC converters, and battery chargers in development, production, and incoming inspection applications. The 63112A is compatible with the 6310 series mainframes and can be paralleled with other modules for even higher power applications.

Key Features

• Maximum specifications: 240A, 80V, 1200W (takes 4 slots in mainframe)
• Four operation modes: Constant Current (CC), Constant Resistance (CR), Constant Power (CP), and Constant Voltage (CV)
• Dynamic loading with programmable slew rates from 0.32mA/s to 10A/s
• Dynamic loading speeds up to 20kHz for transient response simulation
• 16-bit precision voltage and current measurement with dual-range
• User-programmable sequences: up to 100 stored operating sequences in EEPROM
• OCP (Over Current Protection) testing with automatic detection
• Remote sensing capability for accurate measurements
• Full protection: OV, OC, OP, OT, and reverse protection
• Parallel operation capability for increased current and power
• Digital I/O interface for automated testing systems
• Remote control via USB, GPIB, or RS-232 (mainframe dependent)
