The LVR series extends the proven PolySwitch technology of resettable overcurrent protection into higher voltage applications.
When installed in proximity to potential heat generating components such as magnetics, FETs, or power resistors, the thermally active devices can help protect against both over-current and over-temperature faults in power supplies, transformers and control circuits.
The properties of the LVR device offer distinct benefits in transformer protection designs.
The surface temperature of the LVR device in the high resistance state is well within the range of most transformer winding insulation ratings.
This low temperature operation, combined with small sise, low resistance and good thermal shock tolerance, can allow the LVR device to be mounted in direct contact with the transformer windings for a faster response to potential fault conditions.
UL and TUV (IEC) recognised, these solid-state devices are suitable for use in applications including: mobile phone chargers; appliance (range, washing machine, HVAC) control boards; cordless phone and answering machine power supplies; metering, industrial control boards; switching power supplies; transformers, lighting dimmers and ballasts.
