Feature

Frequency 1000Hz compatible (10kW model only)

(Factory option: AX-OP18)

Works seamlessly from 5Hz to 1,000Hz

It responds from 5Hz, which is the low frequency range necessary for motor simulation, and supports the base frequency of the motor inverter from 5Hz to 1,000Hz (accuracy guaranteed: 5Hz to 800Hz). This is the only AC electronic load in Japan with a wide band of 5Hz to 1000Hz. (according to our research)

Compatible with motor inverters (PWM output)

It is possible to perform evaluation experiments without using a motor emulator or an actual motor by smoothing the PWM output from the motor inverter with a filter. Also, since it is not a dedicated tester, it can be used for a wide range of experiments as a general-purpose AC electronic load.

Frequency 400Hz compatible (10kW/50kW model)

(factory option)

The standard frequency range is 40 to 70Hz, but if you specify an option, AC 400Hz (380Hz to 420Hz) for aircraft and ships can be supported. Custom-made options are also available for seamless response from 40 to 420 Hz. It can also be applied to the evaluation and testing of industrial motor inverters (a separate smoothing inductance is required).

CF mode (crest factor setting)

The crest factor (crest factor) can be arbitrarily set in the range of 1.4 (sine wave) to 4.0 in steps of 0.1. This enables testing that reproduces the crest factor of a capacitor input type switching power supply.

PF mode (advance/lag current phase setting)

Capacitive load (C), resistive load (R), and inductive load (L) can be simulated with one unit. The phase can be set in the range of -90deg to +90deg, and can also be set by power factor. Best suited as an inverter output load.

GCC/GCR mode

(Factory option for generator output: AX-OP10)

Even if the output waveform contains distortion like an engine generator, the new load modes GCC and GCR can stably take the load.

Grid connection (regeneration)
