Introduction

The Switched DC Power Hub is a power hub providing four separately fused power

outputs. Each output is equipped with:

a) A switched DC power connection that can be used to power electric locks and any

other devices that require power to be removed under certain conditions.

b) An unswitched DC power connection.

A single Control Input is provided that is connected to Dry contacts or a DC voltage from

a control system. This allows the control system to disconnect power to locks, etc.

under certain conditions to provide free access at access controlled Doors.

Link options allow the Control Input to be configured for Dry Contact or Voltage control

and to nominate which Contact state or Voltage state will turn the outputs On.

A Relay output is also available to provide feedback to a monitoring system to indicate

the current state of the outputs.

NOTE: Voltage control and Relay feedback are not available on the RevisionA PCB.

Specifications

Installation

NOTES: i) Minimum cable type for Power Supply wiring on T1, T3, T4, T5 and T6 is 14/0.20 cable (21AWG). Heavier guage cable may be required depending on load requirements.

ii) Outputs are not isolated and ALL 0V connections are common including the 0V connection on the “Control” Input.

1) The Switched DC Power Hub Board can be mounted in a suitable location, where the PCB mounting holes align with the holes in the chassis, by one of the following methods:

a) In a suitable Inner Range Concept Low Profile enclosure or Integriti enclosure using the 4 Metal Mounting Clips provided.

b) In an Inner Range Concept enclosure where provision is available for use of Hex metal spacers purchased separately. Inner Range P/N: 999003.

2) Locate the host Power Supply that will be used with the Switched DC Power Hub. Disconnect the Battery from this Power Supply, then turn the Power Supply off.

3) a) Connect the output of the host Power Supply to T1 “+12V” and “0V”. Extra terminals allow additional conductors to be used to increase current capability and reduce voltage drop.

b) Connect the required switched (“OUTSW”) and/or unswitched (“OUT”) 12V outputs to lock circuits and any other devices according to your system configuration.

4) a) Set LK2 (“Control”) to the required option depending on the type of output from the Control system. i.e. “Contact” for Dry contacts. “12V-24V” for DC Voltage.

b) Connect the Control System’s control output to T2 “=>” and “0V”. If Voltage control is used, check for correct polarity.

c) Set LK1 (“Output ON”) to “Short/0V” or “Open/12V-24V” according to the table on page 4. The Link nominates which Control Input (T2) state will cause the switched outputs to be ON.

5) If the state of the switched output is required to be monitored, connect the required terminals of the T7 “Feedback” connector to an Input on the monitoring equipment. Terminal labels refer

to the contact states when outputs are On. i.e. COM & NC are shorted when O/P is ON. Refer to the Input wiring instructions for the monitoring equipment for specific wiring details.
