To Mao-phase AC load box | Switching Power Supply AC load | inverter test dummy load single-phase AC load box Product Description: single-phase AC load box used in various types of switching power supply, power supply and inverter IF aviation routine maintenance tests , engineering inspection, factory inspection and product testing aging. Single-phase AC load box uniform segmented power input, energy style mode, forced air cooling, greatly to ensure the reliability of constant power discharge; internal cooling element dry resistance, forced air cooling. Intellectual property used in the production of new power components, high power density, no red-hot phenomenon, automatic overheat protection, in case the fan does not turn, do not overheat, burning, the security and long life; machine modular design, simple operation, easy maintenance; to test voltage, current and other parameters according to customer requirements for high-power AC power supply provides a scientific means of detection. Single-phase AC load box Features: 1, when newly installed equipment, project acceptance UPS detects UPS equipment and battery output power can meet the design requirements. 2, UPS, switching power supply equipment daily maintenance routine testing. 3, the user can performance parameters, testing requirements, set discharge power adjustment, set the discharge time, regular time to automatically turn off the load. 4, test data, power, voltage, current, frequency, so the important parameters at a glance. 5, all the high-performance electric heating elements are in line with UL safety requirements. 6, with a fan failure detection, automatic blocking of overheating protection function, with and machine function. 7, more than parallel discharge, in order to adapt to the large current discharge of the occasion. Single-phase AC load box Applications: detection on cable flow capacity, output power and load capacity with aviation power exchange regulator, inverters, switching power supplies and other communication equipment, communication.
