Elevator Brake Release Device

Model: SJT-EPD110/220

Description of Elevator Brake Release Device

The new EPD series electric elevator brake release device supports independent wiring of dual brakes, meeting the requirements of new regulations. When used in conjunction with the control system of the provincial door lock and emergency stop contactor, the door lock contacts in the control cabinet can be directly utilized, saving wires and ensuring reliability. The elevator rescue device provides battery power output terminals, as well as externally led terminals for the door zone indicator light and externally led terminals for buttons. Adopting a battery compartment design, without disassembling the machine, simply push open the battery compartment cover on the back to easily replace and maintain the battery.

For products of PN/PT/PF/PS models, all use the emergency power supply port. When used in conjunction with the BlueLight VM3 mainboard, the LED digital block on the mainboard can display the car's sliding speed and direction during elevator emergency rescue. 

1. For products of the PT model, the output power of the 24V power supply is increased to 50W. When the electric elevator rescue device is working, the elevator emergency rescue device can directly supply power to the entire 24V system, and the door zone switching power supply no longer requires separate wiring.

2. For the split product of the PF model, it adopts a separated design of the storage battery and the product. The product is maintenance-free, which is convenient to meet the needs of long-term storage or long-distance transportation (such as overseas sites). The storage battery can be purchased and installed on-site after arrival, eliminating the inconvenience of regular charging and discharging management of the storage battery. In addition, the height of this model product is only 108mm, which can be matched with ultra-thin control cabinets.

3. For products of the PS model, by replacing the battery with a larger capacity, the brake output power is increased to 600W, meeting the use requirements in more scenarios.

Features of Elevator Brake Release Device

1. The elevator emergency rescue device has advanced PWM control technology manipulates the output voltage more precise.

2. The elevator rescue device has smart recharging strategy keeps the battery in proper condition and extends battery life.

3. Enable the door zone signals input (Reed Induction Levelling Switch Signal or Infrared Optoelectronic Levelling Switch Signal), to activate the brake and stop the car when the car is in door zone. Passengers can be rescued easily.

4. Enable door inter-lock signal input. Brakes the car when the inter-lock circuit is broken, increases safety.

5. User-friendly and intelligent operations make the installation and application much easier.

6. The elevator rescue device has world class international brand accumulator provides better performance and long-lasting time.

7. The elevator brake release device is a new generation intelligent elevator emergency rescue device, specially designed for elevator without a machine room, to release the brake when the system loses power.

8. With the elevator rescue device, MU_V61 VM3 mainboard can show car sliding direction and speed.
