DAC-HRE-1

DAC-HRE-1 enables measurement of coil resistance of motors, transformers, etc. under energized in AC regarding electrical appliances.
It is according to JIS5311. The direct reading of resistance is possible with 4-wire measurement method on condition that an AC voltage is applied to electrical equipment.
The temperature of specimens is calculated by CPU from resistance and displayed.
You can print out measured values with the optional thermal printer.

DAC-HRT-1

DAC-HRT-1 enables measurement of coil resistance of motors, transformers, etc. under energized in AC regarding electrical appliances.
It is according to JIS5311. The direct reading of resistance is possible with 4-wire measurement method on condition that an AC voltage is applied to electrical equipment. And the temperature of specimens is immediately calculated from measured resistance values and displayed.
Thermal Printer, Selection Control Box, and Pt-100 Temperature Sensor are available as optional items.

DAC-PT-100

When DAC-PT-100 is connected to DAC-HRT-1, it is automatically possible to import ambient temperatures.
DAC-PT-100 is useful to acquisition of temperatures from start to finish of test: initial temperatures, final temperatures, etc.

DAC-SCB-2

DAC-SCB-2 is a ten-channel switching device to connect with DAC-HRT-1 for switching 10 specimens and measuring their resistances.

DAC-HRI-3

DAC-HRI-3 is suitable for temperature tests of AC energized coils of EV (Electric Vehicle) motors, DC brushless motors, compressor motors, etc.
You can measure resistances of electrical equipment driving with an inverter power supply (PWM) under energized conditions.

A DC cut capacitor is necessary for using Hot Line Coil Resistance Measuring Equipment.
It blocks a testing DC current so as not to flow into a power supply driving a specimen.
You should select it in accordance with rated currents of specimens.

DAC-HRM-1/2

DAC-HRM-1/2 is a measuring instrument for shielding-layer resistance of power CVT cables, etc. under current-carrying conditions. Controlling shielding-layer resistance is useful to prevention and maintenance of cable deterioration. DAC-HRM-1/2 is the most suitable for power cable tests on site where it is not easy to break power supply, such as substations, power stations, plants, etc.
