DURABLE MATERIAL: The coating is made of PC material, which ma good insulation, high temperature resistance and anti-aging, and silver contact can greatly improve conductivity. 5. . Dual Automatic Power Switch . Dual Automatic Power Switch Specification: Item Type: Dual Automatic Power Switch Material: PC, silver Number of poles: 4 pcs Insulation voltage: 4000 (V) Rated voltage: 400 (V) Product category ATS: Type CB with micro gap Conversion time: less than 3 s Operating Frequency: 50, 60 Hz Rated impact withstand voltage: 4KV Rated voltage range 3C: 37 V-230 V . Dual Automatic Power Switch . Dual Automatic Power Switch How to use:1. Regardless of the commonly used working and backup power supply with or without voltage, manual operation mode can be used. Manual operation, should be manual setting of the automatic button in manual position,when pressing the hand clockwise do clamp,backup power supply do perform QR switch off,common power supply do make the QN switch close;after turning the handle in the opposite direction do clockwise do clamp,The backup power supply to turn off the QR switch closes the common power supply to turn off the QN switch. 2. In the panel, the power indicator (yellow) indicates that the automatic control box is running powered, if the light does not turn on, indicating that the automatic control box is working power failure, there is a switch. To fix the normal , manual and automatic button set to the automatic position state , if the common power supply is normal , the switch with transition resistors will automatically put into the state of the common QN power actuator on the closing , the R (green) power indicator on the panel lights up . .
