Haydon Power Supply Units

Start from the voltage and current the equipment needs, allow some headroom, then decide whether the supply must keep running on battery when the mains fails.

Battery-backed boxed supplies

Boxed supplies charge a standby battery and keep the load running when the mains fails. The HAY-PSU12V1ABB, HAY-PSU12V2ABB and HAY-PSU12V3ABB give 1A, 2A and 3A at 12V DC, and the 2A and 3A models run at 13.8V to charge 7Ah batteries. For 24V DC, the HAY-DC24V1ABBLPSU, HAY-DC24V2ABBLPSU, HAY-DC24V5ABBLPSU and HAY-DC24V10ABBLPSU give 1A to 10A from a universal 90-264Vac input. The HAY-DC24V1ABBLPSU and HAY-DC24V5ABBLPSU have lid-open and box-removal tamper detection, and the HAY-DC24V5ABBLPSU also has a mains fail output relay.

Fire alarm and access control

For fire alarm systems, the HAY-PSUEN54-1A, HAY-PSUEN54-2A and HAY-PSUEN54-5AL are EN54-4 power supplies with a 27.6V DC uninterruptible output, battery monitoring and volt-free fault signalling; the 1A and 2A models take two 7Ah sealed lead-acid batteries. For access control, the HAY-ACCESS12/24V8/4A-8W switches between 12 VDC at 8 A and 24 VDC at 4 A, charges standby batteries and has eight fused, independently switched outputs with a trigger relay.

Multi-output, AC and inline supplies

Multi-output supplies power several devices from one unit: the HAY-PSUMULTI5A has 9 fused outputs sharing 5A, and the HAY-PSUMULTI10A has 16 outputs sharing 10A. For 24 VAC cameras, the HAY-PSU4/2-2/4A24 gives four 2A or two 4A outputs with auto-reset PTC fuses, and the HAY-IP-24VPSU-1X4A is an IP66 outdoor unit with a single 4A output. Inline supplies include the HAY-PSUINLINE3A24 (24 VAC 3A), the HAY-INLINE 3.5A (12VDC 3.5A) and the HAY-48V2.5A (48V DC 2.5A).
