Model Q-2 & Q-4

Two and Four Channel Power Supply

®

Provides two or four
unregulated 24 VDC outputs
rated at 300 mA

Four input voltage
congurations:

• 120 VAC / 50 Hz

• 120 VAC / 60 Hz

• 240 VAC / 50 Hz

• 240 VAC / 60 Hz

Outputs can be paralleled for
increased current capacity

Power switch controls input

120V or 240V: 120V = 120 VAC input voltage, 240V = 240 VAC input voltage
2 or 4: 2 = Two outputs, 4 = Four outputs

The Model Q-2 and Model Q-4 power supplies transform 120 / 240 VAC, 50 / 60 Hz input power into unregulated
24 VDC. Each output is rated for 300 mA of load current and can be paralleled (via the rack wiring) for increased
current capacity. The Model Q-2 has two outputs, the Model Q-4 has four outputs. The Model Q-2 and Model
Q-4 are available in four input voltage congurations: 120 VAC / 50 Hz, 120 VAC / 60 Hz, 240 VAC / 50 Hz, and
240 VAC / 60 Hz. When ordering, be certain that the power supply input voltage and frequency match the card
rack input voltage and frequency conguration.

Model Q-2 & Q-4 Specications

This is a Performance Specication. It is not intended to be used as Operating Instructions.

General Description: The Model Q-2 and Model Q-4 power supplies transform 120 / 240
VAC, 50 / 60 Hz input power into unregulated 24 VDC. The Model Q-2 has two outputs, the
Model Q-4 has four outputs. Each output is rated for 300 mA of load current and can be
paralleled (via the rack wiring) for increased current capability. The Model Q-2 and Model
Q-4 are available in four input voltage congurations; 120 VAC / 50 Hz, 120 VAC / 60 Hz, 240
VAC / 50 Hz, and 240 VAC / 60 Hz.

Detector Channel Capacity: The Model Q-2 can provide power for up to eight (8) detector
channels. The Model Q-4 can provide power for up to sixteen (16) detector channels.
Detector channel capacity ratings are per NEMA TS 1 / TS 2 standards.

Output Indicators: Each output circuit has a high intensity, red light emitting diode (LED)
that provides an indication of the output status. The indicators are illuminated when the
circuit output voltage is greater than or equal to 20.0 ±0.2 VDC and are extinguished when
the circuit output voltage is less than 20.0 ±0.2 VDC.

Power Switch: A power switch mounted on the front panel controls the input line voltage.

Fuse Protection: Each output circuit is protected by a 0.375 Amp fuse mounted in a PC

board mounted fuse holder. The Model Q-2 has two (2) fuses, the Model Q-4 has four (4)
fuses.

Circuit Board: Printed circuit boards are 0.062 inch thick FR4 material with 2 oz. copper on
both sides and plated through holes. Circuit boards and components are conformal coated
with polyurethane.

Connector: 2 x 22 contact edge card connector with 0.156 inch (0.396 cm) contact
centers. Key slots located between pins B/2 & C/3, E/5 & F/6, and M/11 & N/12. (See Pin
Assignments table.)

Operating Temperature: -40º F to +180º F (-40º C to +82º C).

Weight: Model Q-2: 1.50 lb (0.68 kg).

Model Q-4: 2.65 lb (1.20 kg).

Size: 4.50 inches (11.43 cm) high x 2.00 inches (5.08 cm) wide x 6.88 inches (17.48 cm)
deep (including connector, excluding handle). Handle adds 1.00 inches (2.54 cm.) to depth
measurement.
