Agilent/Keysight MP4361A

The Agilent/Keysight MP4361A is a 1 kW solar array simulator (SAS) DC power module that replicates solar array output characteristics with current-source behavior and minimal output capacitance. Rapid I-V curve alterations enable accurate simulation of various solar arrays under different environmental conditions—temperature, age, eclipse, and spin—without field replacement. The module operates as part of the MP4300A Series and requires a compatible mainframe (sold separately).

– Key Features

Operating Modes: Simulator/Table Mode generates smooth I-V curves from a 1024-point table per output within 8 ms of command receipt. Fixed Mode operates as a source or load with standard rectangular I-V characteristics. Auto-ranging capability optimizes output impedance across the voltage and current range.

Power Management: Bidirectional operation supports both sourcing and sinking. Load operation mode enables multi-module configurations. Built-in over-voltage, over-current, and over-temperature protection.

System Architecture: Modular design rear-loads into MP4300A Series mainframes for minimal installation and service time. A single 2U mainframe accommodates up to six SAS modules at high power density. Mainframe fault detection resolves module failures within 10 microseconds and triggers coordinated shutdown to prevent hazardous conditions.

– Typical Applications

Spacecraft power subsystem testing, solar array characterization under eclipse and thermal cycling, satellite attitude control and spin simulation, power distribution unit (PDU) qualification, and battery charge regulator validation.

– Compatibility & Integration

The MP4361A integrates with MP4300A Series mainframes: MP4301A accepts 200/208 VAC input; MP4302A accommodates 380/400/480 VAC input. Mainframes are sold separately.
