Great thanks

### ⭐⭐⭐⭐ Access control
*by R***W on 15 October 2025*

Cheap and cheerful, does the job well

### ⭐⭐⭐⭐⭐ More than a power supply
*by L***Y on 15 December 2022*

I bought this because I needed a power supply for a Maglock. But it’s a lot more than that For the money it’s brilliant valve as it will protect you primary switching device. It meant for me, my £1,000 Intercom was safer. Remember when a magnet switches off it induces a massive back emf which can burn out relays etc. This device sits between the 2 so will shoulder any damage.
