The NH Research 4700-1 DC Electronic Load is engineered for high-power applications such as DC supplies, telecom rectifiers, fuel cells, and batteries. It integrates measurement functions, eliminating external instruments for dynamic turn-on and turn-off testing. With advanced protection against over-voltage, over-current, over-power, reverse-voltage, and overheating, it ensures safe and reliable performance. Its 100-step macro-recording allows precise recreation of complex load profiles.
This modular, synchronously controlled, and power-balanced unit enables efficient parallel operation as a single load. It supports demanding applications, including CR load turn-on tests, full V-I curve validation for Lithium-Ion chargers, and protection verification to prevent UUT failures during testing.
Testwall can supply the used NH Research 4700-1, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality. Please contact us directly if you need calibration or repair of the NH Research 4700-1.
