Check out our range of security power supplies below. Every system will require power in some form. We offer options to suit a variety of power supply requirements, including both 12v and 24v DC power supply units in 1, 2, 3 & 5 amp versions. We also supply transformer rectifiers and maintenance-free rechargeable batteries. We have a range of regulated power supplies in 12VDC and 24VDC that can house rechargeable battery backup if required. Transformer Rectifiers do not require battery backup and are ideal for use with electromagnetic door closers and hold open magnets. In the event that a fire alarm is activated, the transformer switches off the supply output to the closers or hold open devices and allows the door to close. The fire alarm system needs to be interfaced or a fire relay should be used. No matter what you're looking for, our products are made from the highest quality materials, and our expert team is on hand to provide you with the best possible service. With over 20 years of experience in the industry, we are the go-to choice for anyone looking for reliable and affordable cable management solutions.
