Chroma 6314A Electronic Load Mainframe

Overview

The Chroma 6314A is a mainframe for the 6310A series modular electronic load modules. It can accommodate up to four load modules in a 19-inch instrument rack configuration, delivering flexible testing solutions for multiple output switching power supplies and DC-DC converters. The mainframe enables synchronized parallel operation of all installed modules, allowing users to control multiple loads simultaneously or configure them independently for multi-output testing applications.

Key Features

• Supports up to four 6310A series load modules
• Total power capacity: 1200W parallel load with 240A total current
• Operating modes: Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), and Constant Power (CP)
• Dynamic loading capability up to 20 kHz with internal pulse generator
• Programmable slew rate from 0.32 mA/μS to 10 A/μS for transient response simulation
• Built-in voltage, current, and power measurement with remote sensing
• Minimum input resistance enables high current operation at low voltages
• User-programmable 100 sequences with front panel input status display
• GO/NG testing outputs for automated pass/fail testing
• RS-232 interface standard; optional GPIB and USB interfaces
• 19-inch rack mount design for system integration

Applications

• Testing multiple output switching power supplies
• DC-DC converter performance verification
• Battery charger simulation in constant voltage mode
• Automated production line testing with GO/NG output
• Real-time power supply load transient response analysis
• Over-current protection (OCP) circuit testing
