There are two kinds of product series of power -cut magnetism sustaining unit: the product series GTBM is designed rated voltage mode controlling type;series LPBM has the function of power-cut magnetism sustaining as well as magnetism regulating,which can easily control the pieces of being handled steel plates by field exciting voltage to adjust the electromagnet freely.These product series are update modifications through technical diagnosis based on the original product series GTB6 and LPB1, which improve the operational reliability and technical advantages.Thus,the service work for the customers is obviously minimized.

Main features

1. It will auto changeover the power supply in case of sudden power-cut of transmission -line system of electric power during operation.The holding materials will be gearanteed not to fall down during the set time, and the band -type brake of the hoister will be open to release the attached materials down to the ground safely.
2. The unit has complete integration provided special charging equipment and wonderful testing & display alarm system.
3. Using valve controlled all sealed non -service plumbic acid butteries,acid butteries,auto -charging without man -watching.The butteries will auto -changeover the charging mode by self monitoring.It has a long durability.
4. The unit is light and compact.There is no special requirement for installation;easy and convenient to be serviced.

Product series GTBM2 has extra crane ups power source based on product series GTBM1, with following functions:

1. Input DC voltage 220V provided by the accumulator and output 3-phase AC 380V50Hz.
2. It can control the movement of the cart of the carane when the attracted material can't be unloaded at power failure.
3. It can control the AC brake of lifting device at power failure.no need to replace the AC brake to DC brake.

Attentions for model selection

1. The rated voltage of the electromagnet is in conform with the output voltage of the equipments;The total current (consumption power) of the electromagnet shall he less than or equal to the output current (power) of the commutation controlling units.
2. Electromagnetic band-type brake of lifting device of the lift equipment shall be changed into DC electromagnetic band-type brake when the UPS power source of the crane is not available.
3. Environment working temperature shall be over 50℃,If there is offer special requirements for modification.enlarging the capacity and etc,shall note controlling cabinet when ordered.
