PS07 24Vac Transformer

The PS07 transformer is manufactured by Relcross specifically for use with low voltage electromagnetic hold open door closers. Special transformers with higher ratings can be manufactured to meet applications where large numbers of door closers are used within close proximity of each other.

This transformer can be used also with any manufacturers’ electrified locks and accessories so long as the rating and operational expectations are checked carefully. Please contact the sales office to discuss available options.


The PS07 transformer is designed to meet the requirements of installations where fire and life safety is essential. Each transformer includes a fire alarm relay as standard. This is designed to take a signal from the fire alarm system; releasing the doors from their normal ‘hold open’ position allowing the doors to close and form the necessary fire compartmentation barrier.
