HP312CX: Power Supply/Charger Kit
1Overview
The HP312CX switching power supplies/charger kit converts low voltage AC input into 6 VDC or 12 VDC @ 2.5 A of
continuous supply current, or 1 A @ 24 VDC. 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 (p/n HPS3), a plug-in transformer, steel enclosure (p/n HPB407), 5 Ah 12 V battery,
battery leads, and connecting hardware.
2 Specifications
• Switch selectable 6 VDC/12 VDC.
– At 6 VDC or 12 VDC, the output is 2.5 A total; at 24VDC, the output is 1 A total.
If a battery charger is used, subtract max charge current of 400 mA from total to determine allowable load.
– Input HPS3: 2.3 A max at 24 VAC 60Hz, Transformer: 0.5 A max at 120 VAC 60Hz
• HP312CX includes the power supply (HPS3) and a 24 VAC thermally limited 50 VA plug-in transformer.
– Do not use enclosed battery for 6 VDC output; use a 6 VDC, 5 Ah battery (suggested: Powersonic PS-650L).
• UL-listed to UL294 Access Control Systems and UL2044 CCTV Equipment.
• Filtered and electronically regulated output.
• Built-in charger for sealed lead acid or gel type batteries.
• Stand-by specification:
– At 6 VDC, unit provides one hour of stand-by at 1.7 A with a 6 V, 5 Ah battery.
– At 12 VDC, unit provides one hour of stand-by at 2.1 A with a 12 V, 5 Ah battery.
– At 24 VDC, unit provides one hour of stand-by at 600 mA with two 12 V, 5 Ah batteries.
• Automatic switchover to stand-by battery when AC fails.
• Thermally limited design.
• Circuit breaker battery protection.
• AC input (green) and DC output (red) LED diagnostic indicators.
• Hinged cover and vented enclosure with five convenient knockouts.
• Temperature range: 32ºF to 120ºF (0ºC to 49ºC); indoor use only.
• Enclosure dimensions: 10" H x 11.5" W x 4.875" D (25.4 cm H x 29.21 cm W x 12.38 cm D).
3 Installation Instructions
1. Unpack product. Do not discard packing materials until installation and checkout are successfully completed.
2. Pre-drill holes where enclosure is to be mounted. Choose a vertical surface, strong enough to support the full weight
of the assembly, located in an area without excessive amounts of moisture. Indoor installation only.
3. Secure enclosure to the desired location, using appropriately sized fasteners that can support the full weight of the
assembly.
4. Configure power supply using dip switches to select output voltage desired.
5. Mount power supply inside enclosure with snap-in stand-offs supplied as shown in Figure 1.
