LDU is proud to announce the release the our new 3 phase GATEKEEPER DIN rail mounted surge protection device. The GKSD3 has been remodelled with a new look in a compact DIN compliant metal enclosure retaining the same level of quality and reliability as the previous version. Available in 100 and 150KA sizes the GKSD3 and with LED segmental indication and Alarm contacts as standard.
The GKSD3D is our new flagship of the forthcoming product range in Power Surge Protection.

Manufactured by the LDU Group in Western Sydney NSW Australia, the Gatekeeper surge protector, AKA as a surge diverter has been designed to provide high energy surge protection ideal for Class 1 & 11 applications. These are also known as a surge arrestor or surge protector.
The Gatekeeper continuously monitors the AC sinewave. Once a surge or spike is detected which exceeds the clamping voltage is detected the MOV segment reacts conducting the excess voltage to ground.
The MOV segment will continue to do this until it has reached its life expectancy and expires. The indication on the front of the surge protector continually monitors the MOV segment and once the MOV expires the state of the indication changes and the LED extinguishes. If this should occur we recommend you consider changing the SPD at the next maintenance cycle or earlier if possible as the diverter now has a reduced capacity. The expiration of the MOV component will also activate the alarm circuit.
The Gatekeeper surge protector is available in 3 sizes. 50KA, 100KA and 150KA. Voltage free alarm contacts is a standard feature.
The Three phase version of the Gatekeeper surge protector is operated the same as the single phase version except it has 3 phases. As with the single phase version each of the MOV segments are monitored and will extinguish once the MOV segment expires. Again, this event will activate the alarm.
The Gatekeeper surge protector is available in 3 sizes. 50KA, 100KA and 150KA per phase. Voltage free contacts alarm is a standard feature.
Heavy Duty: Single and Three Phase
The Gatekeeper surge arrestor 210 and 320 operates on a similar principle as the smaller units, however these SPD's have phase monitoring only with a single LED indicator for each phase. The Label is a multfunction label which can be used on either a single phase SPD or a three phase SPD. The indication monitors the state of the MOVs in each phase and when a MOV expires then the indication extinguishes. Once the indication has extinguished the we recommend you change the SPD ASAP as the protection for that phase has expired. The exiration of the protection will also change the sate of the alarm causing it to activate.
Voltage free alarm contacts are a standard feature.
The Gatekeeper surge filter has been designed to provide high energy surge protection for Class 1 & 11 applications, ideal for protecting sensitive electronics. Boasts a massive 50KA of surge diversion when compared to the standard filter which has a max 8-20KA. Availble for Single phase 8 Amp, 10 Amp, 16 Amp and 32 Amp applications. Also available in weartherproof enclosures.
