Compact Resistive Load Bank Ideal for Onsite Testing and Commissioning of Electrical Generators and Backup Power Systems

1. 10 kW across three output channels, 12 stackable steps starting from 10 W Load steps are 10 W, 20 W, 20 W, 50 W, 100 W, 200 W, 200 W, 500 W, 1 kW, 2 kW, 3 kW and 3 kW. They can be combined freely, giving a minimum step of only 10 W and a maximum of about 10 kW (step total 10.1 kW) — one unit covers everything from light-load verification to full-load burn-in.

2. Forced-air straight-through cooling rated for 7×24 continuous duty Front-to-rear airflow with nine 15050 axial fans (220 VAC) provides ample thermal headroom for continuous on-line loading in burn-in rooms and test benches running around the clock.

3. Digital metering, per-channel breakers and multiple protections A digital meter displays voltage, current and power with no external instruments needed. Three circuit breakers control the three output channels independently. Over-current protection is standard; over-temperature alarm, over-voltage protection, fan-failure alarm and emergency stop are optional.

4. Integrated mobile cabinet, ready to use on site The 700 × 600 × 860 mm, 85.5 kg cabinet rolls on casters. Resistor output is via three sets of threaded terminals, plus one AC 220 V auxiliary power socket (HC-99). With IP20 rating for indoor use and ±1% resistance accuracy, it can be connected and put into service immediately.

1. Factory load testing and burn-in of generator sets, UPS systems, inverters and energy-storage PCS Simulates a true resistive load to verify output voltage, current, power and load stability, replacing crude setups such as resistance wire or water resistors.

2. Burn-in rooms for switching power supplies, charging modules and DC power supplies The 7×24 duty rating and 12 fine load steps allow burn-in profiles tailored to different power levels, while three output channels can carry several units under test at the same time.

3. Temperature-rise and current-carrying tests on distribution equipment and components For circuit breakers, contactors, cables and terminal blocks, test current is set precisely by stacking steps, and readings come straight from the digital meter.

4. Load simulation, calibration and troubleshooting in labs, universities and inspection bodies Serves as an adjustable resistive load for performance comparison, power calibration and fault reproduction of power products, and is also used for the safe discharge of capacitor banks and battery packs.

Q1: Is this a three-phase unit? What does "3 channels" mean? A: No. This model is single-phase AC 220 V with a rated total of 10 kW. "3 channels" means three independent output circuits, each with its own threaded terminals and circuit breaker, which can be switched in or out separately — not A/B/C phases. Three-phase applications require a three-phase model.

Q2: What is the minimum and maximum load? A: The smallest step is 10 W and the 12 steps can be stacked to roughly 10.1 kW, i.e. the 10 kW rating at full load. Adjustment is by step stacking, not stepless; intermediate values are approached by combining adjacent steps.

Q3: Can it really run 7×24? Under what conditions? A: The unit is designed for continuous on-line duty and supports a 7×24 regime, provided that ambient temperature stays within −10 to 50 °C, the environment is dry and ventilated, the intake and exhaust are unobstructed with clearance front and rear, and the 220 VAC auxiliary supply for the nine fans is connected — otherwise airflow stops and overheating protection may trip.

Q4: What protections are included? Can they be customized? What is the warranty? A: Over-current protection is standard. Over-temperature alarm, over-voltage protection, fan-failure alarm and emergency stop are options — recommended as a full set for burn-in room use. Resistance accuracy is ±1% (sheet resistor). The unit carries a one-year warranty.
