Sunwin WN-6 6kW Rack-Mounted Load Bank

1. Product Overview

The Sunwin WN-6 is a 6kW rack-mount resistive load bank designed for low-power equipment test scenarios. Adopting a 6U rack-mount form factor, it supports dual-channel single-phase AC230V input with a maximum of 3kW per channel and a total rated power of 6kW.

By combining 0.5kW, 1kW and 1.5kW load units, the WN-6 achieves fine loading steps of 0.5kW, making it suitable for performance verification, factory inspection and maintenance testing of small-scale generators, UPS units, power modules, inverters and other AC power-supply devices.

2. Key Features

2.1 Compact Rack Design with Portability

With dimensions of only 483×480×267mm and a weight of approximately 25kg, the unit adopts a standard 6U rack-mount structure and is equipped with three portable carrying handles. It can be conveniently installed in standard equipment racks, laboratory test benches or on-site test stations, suiting R&D, factory inspection, maintenance and engineering commissioning applications.

2.2 Dual-Channel Fine Loading

The unit supports dual-channel single-phase AC230V input, with phase A (AC1) and phase B (AC2) each configured with 0.5+1+1.5kW load units (3kW per channel), providing a total of 6 load steps with fine adjustment in 0.5kW increments to meet the precise loaded testing needs of low-power power equipment.

2.3 High-Efficiency Forced-Air Cooling

Equipped with four heavy-duty DC blowers (235 CFM per fan) and a side-airflow design, together with fin-type stainless-steel electric heating tubes and nickel-chromium resistor cores, the unit delivers efficient and stable heat dissipation for reliable long-duration continuous testing.

2.4 Comprehensive Safety Protection

The unit integrates thermal-protection emergency cut-off and MCB circuit breaker protection, with intuitive local control, delivering stable, flexible and safe load-test support for generators, UPS units, power modules, inverters and other AC power-supply devices.
