PS-DC-DUAL-5624T
345 Watt Isolated Power Supply with 56VDC and 24VDC
Dual Output
Quick Start Guide
The Power Supply provides 345W at 56VDC and is targeted for PoE applications.
The Power Supply is fully compliant with IEEE 802.3af, at, and bt PoE standards for
isolation. It provides a secondary fully-isolated 24V at 1.25A (30W) output for other equipment.

Connectors and LEDs
AC Input: IEC C14 Connector; 6.3A slo blo Fuse; Power On/Off switch.
56VDC and 24VDC output: 6-Pin Terminal Block: Pin 1: 24Vout+. Pin 2: 24Vout-. Pin 3: Alarm Contacts 1.
Pin 4: Alarm Contacts 2. Pin 5: 56Vout+. Pin 6: 56Vout-.
LEDs: Power status: Green: OK. Yellow blink: Will cycle through if one or more events (alarms) occur with a Blink Rate:
1blink per 3 seconds: Fan locked (no tach). 2blinks per 3 seconds: Fan less than 30% PWM (Pulse Width Modulation)
setting. 3blinks per 3 seconds: 24VDC output out of spec. 4blinks per 3 seconds: Exceeding -25 Deg. C.
5blinks per 3 seconds: Exceeding +75 Deg. C. If more than one alarm is set the LED will cycle through the Blink Rates one
at a time, and then repeat until the alarm is cleared. The Blink Rates include a 3 second alarm delay to prevent triggering
a false alarm when the fan ramps up or down.
Power Cords: Locking and non-locking line cords are available. See the Install Guide.
Front Panel: shown and described below. See the Installation section for grounding and connection.
On / Off switch: The power on/power off switch is labeled O (off) /|(on).
FUSE: The fuse can be replaced without opening the chassis; see Fuse Replacement in the Install Guide.
AC INPUT Power connection: labeled 100 - 240VAC 50/60 Hz; see Connecting AC INPUT below.
POWER OUTPUT Terminal Block: is labeled 56 VDC - and +, ALARM, and 24 VDC - and +.
Unpacking: Carefully unpack the Power Supply. Verify you have received: one Power Supply, one Postcard, one printed
Quick Start Guide, one AC Power Cord, and four Rubber Feet.
Mounting: Desktop: Attach the 4 adhesive-backed rubber feet to the bottom of the power supply for desktop mounting.
DIN Rail: The power supply ships with a DIN rail mounting bracket attached. Caution: If mounted in a NEMA rated
enclosure, either vertical direction is allowed. In a standard 19” rack, the side holes must face upward. To DIN rail mount
the power supply: 1. Ensure at least 2 inches of open space outside of at least one of the two vented sides. 2. Hang the
top of the DIN rail bracket on the DIN rail. Caution: The DIN Rail Spring Clip must be facing upwards. 3. Click the bottom
of the DIN rail bracket onto the DIN rail.
Grounding: Use appropriate gauge wire to connect the Phillips head Ground screw to ground following your
organization’s grounding procedures.
