High Current Alarm Relay:


Our hall effect high current alarm relays are designed to monitor DC current and deenergise a double pole double throw volt free relay if the measured value rises above a pre-set (via adjustable potentiometer) current value. Typical applications would include any DC powered assembly where high current indicates a fault condition with potentially dangerous consequences such as failure of control in a battery charging system, overload of a battery installation or power supply or some form of partial or dead short.

Additionaly an undercurrent value can also be set separately if required so that the relay also trips if current falls below a preset (via adjustable potentiometer) value. This is useful in applications where current flow is expected to sit within a variable range with a defined minimum to maximum value.

Front panel led indicators for healthy and fault condition are visible through the product label windows. A delay of several seconds between fault detection and relay de-energisation prevents nuisance tripping on systems connected to switch tripping or short duration high demand loads.

A number of different versions are available with self-powered versions suitable for operation on 12V, 24V, 36V, 48, 60V and 110V battery and power supply systems. The unit is also available for higher voltage applications but requires a 12V or 24V supply to power the electronics.

The high current alarm is 90mmH and 50mm square and designed to plug into a standard 11 pin relay base which can be panel or din rail mounted and a base is supplied with the alarm. The hall effect CT is mounted on separate pcb (55mmL, 30mmW, 40mmH) and includes 4 off 4mm includes mounting holes.

Several different current models are available with peak sensed levels of 57A and 100A. The sensitivity of the alarm can be adjusted to detect current levels of 2A upwards.

The alarms are built to order and have a lead time of 3 weeks from receipt of order.
