The AC Loading Unit is used to test the capacity and performance of high-power UPS, power supply, diesel engine sets, etc. The system is built up in a modularized framework, and it is easy to operate and maintain. The power control component adopts the advanced silicon module, the discharge current (power) is adjustable, and thus the discharge power can be kept at constant level, which has highly increased the reliability of the system. The main power-consuming components using superior new-material subassemblies, have the advantages of high power consistency, no red-hot, and automatic overheat protection, thus overheat or burn-up is avoided even the fan is accidentally out of order. The use of minitype single-phase φ150 fans to make dispersed wind supply has significantly reduced the noise output. The AC Loading System Series have been mainly used in the field of telecommunication, electricforce, railway, etc.

Main Features:
1. Adjustable discharge power: discharge power can be adjusted to the testing requirements for the performance parameters.
2. Discharge time setting: the loading system switches off automatically when the timer is up.
3. Automatic overheat protection: the use of alloy resistances and/or PTC components ensures the system will be disconnected when overheated.
4. Available in both single-phase and triple-phase, providing effective testing methods for high-power AC equipments.
