Specifying Power Supplies for Security Applications

Power supplies often perform switching functions, monitor and report their own status, and automatically compensate for changing site conditions such as brown outs, power interruptions, power surges and temporary increases in the system load.


HPP's portfolio of video supplies include both AC and DC power, outdoor weatherproof units, rack mounted products and surge-protected offerings. HPP's supplies operate from 115VAC or 230VAC to provide a constant source of power through individually-fused outputs that operate cameras and other video accessories. Providing 12VDC, 24VAC or 28VAC from 300ma to 8 amps of fully regulated supply current, HPP video supplies have the power to run the majority of video applications within the security industry.

HPP's video products feature incoming power fused on both the primary and secondary side, hinged and vented enclosures with multiple convenient knockouts, a power disconnect switch, input and output transient protection, and individually fused 4, 8, or 16 outputs with LED status indicators for each output. All transformers have built-in thermal overload protection and units contain field-replaceable automotive style fuses (widely available), or auto-reset PTC's that do not require replacement.

The HPTV2401 and HPTV2801 series are power supplies which provide power and surge protection, depending on model, for applications such as access control, security, and video applications. These surge protected power supplies provide superior protection against voltage spikes and transients that can damage or disable expensive and critical equipment.

The HPTV surge protected series consists of thermally fused transformers and an electrically fused primary output.

These units accept 115VAC input and provide a single output of 24VAC or 28VAC. The HPTV2401 and HPTV2801 are single output CCTV power supplies that include no surge protection.

The HPTV2401S and HPTV2801S include an HCPS Surge Module which provides power and video surge protection. The HPTV2401Z and HPTV2801Z include an HDSP1 Surge Module which provides power, video and data surge protection.

HPP's HPTV2401WPS; HPTV2401WPZ; HPTV2801WPS and HPTV2801WPZ are weatherproof power supplies provide power and surge protection for applications such as access control, security, and video applications that require outdoor installation. These surge protected power supplies offer superior protection against voltage spikes and transients that can damage or disable expensive and critical equipment.

HONEYWELL POWER PRODUCTS HPS312CX

This switching power supply/charger converts low-voltage AC input into 6, 12 or 24VDC at 3.0A of continuous supply current. The HPS312CX also comes kitted with an HPP HPT2450 plug-in transformer, 5 AH battery, steel enclosure, and connecting hardware. This general purpose power supply has a wide range of applications for access control systems that require additional power.

Access Control Power Supplies carry both UL and ULC ratings for fire, access control and intrusion systems and have a large enclosure to ease wiring. They feature circuit-breaker battery protection, AC input and DC output LED diagnostic indicators, AC fail and battery monitoring contacts to aid in supervision, and a built-in charger for sealed lead-acid or gel-type batteries.

In addition, the Power Supplies offer a filtered and electronically regulated output, and an automatic switchover to standby battery when AC fails. All of the power supplies are 12vdc or 24vdc field- selectable to meet today's equipment requirements.

The HP512CX switching power supply/charger kit converts low voltage AC input into 6 VDC or 12 VDC @ 4.0 A of continuous supply current or 24 VDC @ 2.5 A of supply current. This general purpose power supply has a wide range of applications for access control, security and CCTV systems that require additional power. For convenient operation, this power supply unit includes the power supply board, transformer, steel enclosure, 5 AH/12 V battery, battery leads, and connecting hardware.
