Outline:
This series is the power-supply & rectifying control equipment as well as the security system of the electromagnet at site. When the electromagnet is working, this equipment can float charge the accumulators. When the electromagnet is under the operation of attraction but the electrified barbed wire is cut-off, it can self-shift the power-supply and prevent the attracted material from dropping, thus assure other equipments and livesl safety at the operation site. It is mainly used in metallurgy, shipyard, port and so on.
GTBM series is specially designed by our company and suitable for normal application. LPBM series is imported advanced technology, which is the updated magnetism regulation and protection equipment. The control equipment we manufacture has the following outstanding characteristics:
1. When the electromagnet is under the situation of attraction and it happens that the electrified barbed wire is cut-off, it can self-shift the 'magnetism protection system' and prevent the attracted material from dropping; at the same time it sends out an alarm the assure other equipments and lives' safety.
2. At the same time of keeping the attracted material, it can control and open the band brake of living crane and put the material on the ground safely.
3. It adopts the automatic charging circuit, constant charging, auto-tracking & shifting at floact charging. It has the function of sending out alarms and controlling if it is over charging or discharging. On the basis of the characteristics of the maintenance-free lead-acid battery, we design the function of current limit and constant voltage, which an fully make use of the battery and extend its service life.
4. If adopts maintenance-free and full-seal battery as prepared power supply featuring long service life and easy to maintain.
5. This unit can work with UPS power-supply of the travelling crane which has the following functions:
1). Input volt,age is DC 220V provided by accumulators and output 380V 50HZ 3-phase AC power-supply.
2). When the electromagnet is under the situation of attraction and it happens that the electrified barbed wire is cut-off, it can control the truck moving if there in not enough conditions to set down the attracted material.
3). When power-cut, it can control the main AC hoist controller, so there is no need to change the original AC controller to DC controller by using this equipment.
GTBM\LPBM Series Model Selection and Attentions:
1. When the magnetic band brake doesn't use the travelling crane UPS power-supply, must use the DC magnetic band brake.
2. The electromagnet's rated voltage must be in accordance with the output voltage of the equipment.
3. The electromagnet's current must be less than or equal to the rated current of the equipment, or the power must be less than or equal to the control power of the electromagnet.
