Power-Cut Magnetism Sustaining Commutation Controlling Unit:
It has two series GTBM & GTBMT.
-GTBM is designed for rated voltage mode controlling type.
-GTBMT: Has the funtion of power-cut magnetism sustaining and magnetism regulating, which can easily control the pieces of being handled steel plates by field exciting voltage to adjust the electromagnet freely.
Rectification Control Equipment GTBM-14E-C Main Features:
-- 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 guaranteed not to fall down during the set time, and the band-tupe brake of the hoister will be open to release the attached materials down to ground safety.
-- The unit has complete integration provided special charging equipment and wonderful testing&display alarm system.
-- Using valve controlled all sealed non-service plumbic acid butteries, auto charging without man-watching. The butteries will auto changeover the charging mode by self monitoring. It has a long durability.
-- The unit is light and compact. There is no special requirement for installation; Easy and convenient to be serviced.
( Ordering Instruction: Contactless power-cut magentism sustaining mode and contactless strong excitation controlling mode are VT-GTBM- & VTO-GTBM-. The technical data are the same. )
Model Description: GTBM-14E-C
G(type code): Cabinet type
TB: Power-cut magnetic sustaining equipment
M: Service free mode
14: Rated output power
E: With discharge loop
C: For indoors
Note:
1. The rate voltage of the electromagnet is in conform with the output voltage of the equipmen; The total current (consumption power) of the electromagnet shall be less than or equal to the output current (power) of the commutation controlling units.
2. Electromagnetic band-type brake of the lifting equipment shall be changed into DC electromagnetic band-type brake when the UPS power source of the crane is not available.
3. If the working environment's temperature is over 50° C, or there is other special requirements such as modifying, enlarging the capacity and so on, please state when ordering.
