Automatic transfer switch RDH5D

double-throwinterlockremotely operated

RDH5D sériés Automatic transfer switch equipmentjntegrates electrical and mechanical interlocking systems to guarantee safe transfer operation.lt is applicable for the industry distribution device power supply system of AC50Hz,rated voltage AC400V, rated conventional current up to 3200A.lt has détection, communication, electrical and mechanical interlocking functions.lt can realize full-automatic and remote control,reset,manual control for emergency and other operations.This switch is applicable for two circuit power supplys, normal and standby power supply changeover automatically or the automatic changeover and safe disconnect between two sets of load equipments. Switch structure 3.1 - Electrical lock: control switch internai circuit power. when it is on, the switch can realize full-automatic, forced recovery and remote opération; when it is off, the switch only can be manual-operate. 3.2 - Opération handle: The electrical lock should be off when the handle is used for manual opération. 3.3 - Mechanism lock: using for détection. Firstly, turn switch to "0" position by using handle, then, pull the lock mechanism up and lock it, then taking detection.(pull up the lock, and the switch internai control power supply would be eut off, the switch can not automatic and manual opération.) 3.4 - Position indication: indicate the working position(l,0,ll). Usage Method 6.1 - Automatic function: when normal power supply is off, the switch transfers the circuit to Backup power supply; when normal power supply is recovery,the switch would transfer circuit to Normal power supply. 6.2 - Forced recovery "0" function: start "0" button, the switch would eut two power supplys.
