JH80V50A-4kW DC electronic load — regenerative type
The JH80V50A-4KW (hereinafter referred to as this load module) is a single‑channel, 4 kW, programmable, energy‑recovering DC electronic load. It features CC (constant current) and CP (constant power) loading modes, along with OCP (overcurrent protection), OPP (overpower protection), and OTP (overtemperature protection). It is suitable for aging tests of AC/DC and DC/DC power converters, such as adapters, chargers, LED power supplies, and DC generators. Key features and advantages: ※ Independent load units that can be flexibly integrated into aging systems. ※ Supports both CC (constant current) and CP (constant power) modes, which can be used in combination. ※ Both CC and CP modes can be paralleled to increase the available load current and power. ※ Comprehensive protection functions, including overtemperature, overcurrent, and overpower protection. ※ Energy‑recovery capability, with conversion efficiencies exceeding 90%, delivering energy savings and environmental benefits. ※ Fully isolated RS‑485 communication. ※ All‑digital control and digital monitoring. Application areas: ※ Standalone aging carts, racks, and chambers. ※ Series‑connected aging solutions for adapters and chargers. ※ Aging equipment for DC generators. ※ Automated aging systems.
