HAI Now Shipping Power Hub for New Access Control Line and General Purpose Power Supply

[electron]

HAI (Home Automation, Inc.), leading manufacturer of integrated automation and security products since 1985, is now shipping the HAI Power Hub, a digital high efficiency power source engineered to meet the forthcoming ENERGY STAR requirements for power supplies and battery backups. It comes in two versions; the 83A00-1 is a Power Hub in an enclosure and the 83A00-2 is a Power Hub on a Universal Mounting Plate. It is designed to provide power to several HAI products, including the HAI Access Control Readers with electric or magnetic locks, Omni Consoles, OmniTouch 5.7 Touchscreens, and many other devices. It is a 12VDC power supply that is mounted in an enclosure. The HAI Power Hub is compatible with both 120/60Hz and 220V/50Hz for International applications.

The HAI Power Hub has convenient connections and power terminals for a neat installation. It is designed to eliminate unsightly transformers, power strips, external power supplies, battery backup units, and complex wiring normally associated with access control installations. It connects up to 8 Access Control Readers to the HAI controller. Two of the Power Hubs may be connected together to connect up to 16 readers to an OmniPro II or Lumina Pro system.

HAI products are available through a worldwide network of Distributors and installing dealers. For more information regarding the new HAI Power Hub or other HAI products, please visit www.homeauto.com or call 800-229-7256.

Although described as "high efficiency", I could find no specs or data or description of the "digital high efficiency" technology used.

From the high-res photo, it does not appear that the supply provides isolation between, or current limiting of the individual channels.

So while it may be well suited for HAI's familiy of devices in approved configurations, folks that try to use it as a "General Purpose Power Supply" ... "to eliminate unsightly transformers, power strips, external power supplies, battery backup units, and complex wiring ..." in non- HAI configurations may not find it suitable despite the billing because:
1) Not all 12vdc grounds of devices in HA systems can be interconnected without unintended interaction.
2) Current limiting for the dozen devices supported may not sufficiently protect individual conductor pairs or devices and
3) If current is limited/disconnected owing to a short, all the powered devices on a common channel will go down, not just those on the offending circuit.

"Course I may not 'read' the photo correctly. I'll be curious to see what the detailed specs state.

The combined output is 5 A which would "possibly" make it Class 2 or Power Limited outputs (I see a few PTC's on the board as well) Is it UL Listed (for those that care)? I assume it is fed by a wall wart transformer since I dont see a connection for mains voltages or grounding of the enclosure. It is possible that the wall wart has a DOE Level IV listing for Energy Star (similar to California CEC Level IV).

These types of supplies are sorely needed but I personally thing they should have 2 outputs that are adjustable to 6 or 9 Vdc etc. for accessories that do not run on 12 Vdc (routers, modems etc).

It does appear to have a wall wart connection (left side, half way up the board is a black plug in connector)

Here's more info on this power hub:

• The hub has connections for up to 8 card readers or consoles (LCD or OmniTouch).
• The hub provides a 12VDC output, up to 5A. This is enough power to control up to 8 card readers with “HAI” door strikes (card reader = 150 mA, door strike = 450 mA).
• The hub is powered by a 110/230 power pack (brick) with a 19.2VDC output, up to 3.79A. The brick is included with the unit.
• There are two sets of battery backup leads – recommend 12V, 4-8 Ah each.
• The hub has 2 RJ-11 connectors:
  • One to connect the hub to an on-board serial port on the HAI controller.
  • One to connect a second power hub (piggy-back) so that a maximum of 16 card readers can communicate to an Omni Pro II through a single serial port.
• The hub has a terminal block for connecting the following on the HAI controller:
  • LB+/- - these two terminals wire to a zone on the HAI controller for Low Battery indication.
  • A (yellow)/B (green) – two terminals for connection to the A/B data bus on an HAI controller when consoles are connected to the hub.
  • GND – used to connect to the Earth Ground terminal on the HAI controller.

The tan, rectangular devices seem to be _across_ the battery and input terminals and so appear to be Metal Oxide Varistors (MOVs) and wouldn't limit output as Positive Temperature Coefficient (PTC) thermistors in series with the output would.

On closer squinting, I see small IC's around the largest inductor and eight sets/arrays of plated pcb through-holes which may connect to MOSFETs, or other output devices, or series common-mode inductors on the other side of the pcb which we can't see. I dunno. Per-channel specs, when available, sh/would tell the story. I don't see an active device or relay for the low-battery cutoff either, so sumthin's going on that we/I can't see ...
