elevator rescue device(elevating),elevator machine,lift elevator controller ELEVATOR AUTOMATIC RESCUE DEVICE HK-ARD-15E INTRODUCTION: HK-ARD-15E ELEVATOR AUTOMATIC RESCUE DEVICE is an elevator safety device specially to improve the elevator safety.The device adopts the original elevator control system and inverter system.We have no develop other driving system not including the original elevator control system,so it has wiring simplymodify convenientlyprice quality highly etc.The passenger will suffer from phsically and psychological harm trapped in elevator when the power system is off.Under the conditions,the device will start to work automaticly within the set time.The elevator cab will run slowly to leveling nearly,opening the door and releasing the passenger. FUNCTION FEATURES: 1.The device is in standby state and charges up storage bettery when the power system is nomal.It will start work upon power cut.And it can switch quickly to standby state when the power system is restored. 2.You can set freely the time from the power system blackout to the device running as for your actual demand.You may solve the question that different inverter removalled trouble signal time is different. 3.Sometimes,the elevator cab need run a long time to levelling due to a long shaft.So,the device need also sent a long time.It is no problem for our device. 4.All the output signal of the device is control by program.For example:running time.So,it is very exact. 5.The storage bettery adopts the most advanced stage pulse charge and the bettery has repair function.It is very fast to charge the bettery.And,it can maximam extend the bettery life. 6.It can display various state of charge according to LED light indication. 7.The bettery is not add liquid.It only need charge and discharge about once a year. 8.Weight:about 30kg.Size small,installtion easy. MAIN TECHNIQUE PARAMETER: 1.Charge: a.charge input voltage:AC220V(AC230V)±10% frequency:50HZ/60HZ b.charge output voltage:DC55V-DC56V c.under constant current,charge output current 3A-4A 2.R.S.T input voltage: three phase AC380V 400V±10% frequency:50HZ/60HZ 3. Invertion output voltage:two phase AC380V±10% 50HZ SINE WAVE MAX output current:3A 4.Evironment temperature: 0 45 5.Storage bettery:4 PCS 12V/12AH series bettery
