• Accuracy: 800 ppm/°C with temperature coefficient of ±0.2 to ±0.8 mΩ/°C depending on range
– Key Features
Load Modes: Constant Current (CC), Constant Voltage (CV), and Constant Resistance (CR) operation
Programmable Control:
• Analog voltage control in constant current mode
• Pulse waveform generation with programmable amplitude, frequency, duty cycle, and slew rate
• Continuous and pulse mode operation
• Programmable minimum battery voltage threshold for battery testing
• Selectable transient response via front panel or remote programming
Protection: Overcurrent, overvoltage, overpower, overtemperature, and reverse polarity protection
Measurement & Readback:
• Front-panel LCD display of voltage, current, and power
• GPIB readback of voltage, current, and power values
• Internal voltage and current monitors
Interface: SCPI-compliant command set with IEEE-488 (HP-IB) connectivity
– Typical Applications
Power supply testing and characterization, battery testing under variable load conditions, DC component evaluation, and transient response analysis of switching supplies and startup behavior.
– Compatibility & Integration
The 60502B module integrates into the HP 6050A mainframe (up to six modules) or HP 6051A mainframe (up to two modules). Test programs developed for the HP 6060B single-input 300 W electronic load are directly interchangeable with the 60502B.
