IEC 62196-1 Resistive Inductive Three-Phase Power Load Cabinet Test Voltage AC100～600V

The Sinuo Three-Phase AC Resistive and Inductive Load Bank is designed for electrical performance evaluation, switching endurance testing, and load simulation of electrical accessories and related equipment. It supports test applications associated with IEC 62196-1:2026 Clauses 22 and 23, IEC 61535 Clause 17, and other applicable test requirements.

This three-phase AC load cabinet combines adjustable resistive and inductive loads, allowing users to configure load conditions for different electrical testing procedures. With an adjustable test voltage of 100–600V AC, a current range of 8–100A, and a continuously adjustable power factor from 0.3 to 0.99, the system provides flexible load configuration for laboratory testing.

The equipment can be used for switch endurance and electrical performance tests involving appliance switches, plugs, socket-outlets, transformers, fuses, and other compatible electrical products. Its integrated chamber-type construction, forced-air cooling, panel-operated load switching, and multiple electrical protection functions make it suitable for indoor electrical safety and product verification laboratories.

• Wide-range three-phase AC output: Adjustable test voltage from 100V to 600V AC for different electrical load testing requirements.
• Combined resistive and inductive loading: Configure resistive loads and inductive loads according to the intended test procedure.
• Adjustable power factor: Continuous adjustment from 0.3 to 0.99 supports testing under different load conditions.
• Fine current adjustment: Current adjustment resolution of 0.1A, with automatic output cut-off when the current exceeds 105A.
• Digital measurement display: Three-phase voltage and current readings, together with digital power factor indication, support convenient monitoring during testing.
• Integrated safety protection: Leakage, overheating, overcurrent, overload, and short-circuit protection functions.
• Forced-air cooling: Built-in fan-assisted cooling for indoor laboratory operation.
• Practical laboratory installation: Chamber-type construction with casters for easier positioning and movement.

The following table summarizes the main specifications of the three-phase load bank for technical evaluation and procurement reference.

This programmable-by-configuration resistive and inductive load system is intended for laboratory applications where controlled electrical loads are required. Actual load settings and test procedures should follow the relevant product standard and test plan.

For laboratories working with IEC 62196-1 requirements, the load bank can provide resistive and inductive load conditions for applicable electrical testing of charging accessories. The intended application includes the relevant test procedures associated with Clauses 22 and 23.

The adjustable load configuration can support applicable switching endurance and electrical performance evaluations of appliance switches and similar switching components under specified test conditions.

The three-phase load cabinet can be incorporated into suitable test setups for plugs, socket-outlets, and related electrical accessories, subject to their rated values and the requirements of the applicable standard.

The resistive and inductive load functions can also be used in compatible test arrangements for transformers, fuses, and other electrical products that require controlled load conditions.

The load cabinet uses groups of resistors and iron-core inductors to establish the required load configuration. Resistive elements are constructed using constantan wire windings, selected for their low temperature coefficient of resistance. Inductive elements can be connected or disconnected as required by the intended test setup.

Operators control the load through push buttons and panel-mounted knife switches. Digital instruments display the relevant three-phase voltage, current, and power factor readings. A built-in forced-air cooling system helps manage heat generated during load operation.

The equipment also incorporates protective functions against leakage, overheating, excessive current, overload, and short circuits. These functions help protect the test system during operation but do not replace appropriate laboratory electrical safety procedures.
