Soken DAC-STM-1 - Stand-alone AC insulation test system
DAC-STM-1 is a standalone and movable test system in one box providing a built-in high-voltage testing power supply. Simplified operations and automatic testing mode change are realized, that is, setting and measuring time can be greatly reduced. Compact in size for testing site, Low center of gravity, it is designed to be very stable and easily even moving with only two wheels. DAC-STM-1 strongly supports to complete quickly your on-site measurement.

UST, GST, GSTg Change Circuit Inside
Conventionally, measuring cables have to be changed in accordance with testing modes. However DAC-STM-1is provided with a change circuits that automatically change CH-L, CH-T or CH-G.
- This instrument has a built-in testing power supply, and is easy to move and set connections, enabling quick setup and start measurement in a moment.
- Introducing high voltage CT method, reliable measurement without being affected by stray current in grounding.
- Providing a change circuit of UST, GST and GSTg mode, automatic measurement through the three mode can be quickly done without changing connections
- Applicable to a transformer with Tertiary winding.
- Providing Induced Emission and Polarity Change, advantageous to test on sites where are prone to inductive interference
