Introduction

• STS series dynamic reactive power compensation switching regulator is a new device used in low voltage reactive power compensation equipment, it can achieve quickly zero switching to the low-voltage shunt capacitor, and it is the ideal device for fast switching of capacitor.

Feature

• Use foreign good brand SCR, high reliability and stability
• MCU control precise trigger, software correction trigger timing for true zero switching
• While switching capacitor, no flow, no overvoltage, no sparks, fast response time of less than 15ms
• Support level and pulse trigger mode, the trigger mode is flexible and easy to replace transform.
• Use optical isolation to avoid interference
• Phase lack alarm with overheat protection
