SPECIFICATION

INPUT SPECIFICATION

OUTPUT SPECIFICATION

Input Range: 2:1 DC input range:

Output Voltage: See Ratings Chart.

4.5-9/9-18/18-36/36-72Vdc.

Output Current: See Ratings Chart.

Voltage Accuracy: Main O/P ±2.0 % typical.

Line Regulation: ± 0.06% typical.

Load Regulation: VO1 ±0.60 %, VO2 ±0.5% typical.

Noise & Ripple: 1.0% typical.

OVP: Built-in on main output VO1.

Adjustability: VO1 O/P may optionally be external

trimmed ±3.0% with a fixed resistors or trim-pot.

Short Circuit Protection:

Power fold back, and self-recovering.

Overload Protection (OLP):

Input Voltage: Nominal 5/12/24/48Vdc.

Input Current: Various with input range and load.

Input Fuse: Use external fuse.

Input Filter: Pi-Network.

Input Reflect Ripple Current: 45mA typical.

Isolation Resistor: 1,000 Mega Ohms.

Isolation Voltage: 1,500Vdc.

EMI: Six-sided metal shielding.

Remote On/Off: TTL/CMOS-Compatible Input Control.

Positive Logic version for Standard set up:

ON(Enable)=Open(or 2.5-5.0Vdc above-Vin)

OFF(Disable)=Short(or 0-0.8Vdc above-Vin)

Negative Logic version option available by adding a

Fully protected against output overload and short circuit.

OLP set at about 125-150% rating output wattage.

Consult the factory for OLP setting.

“N”suffix to the end of Model #.

Remark: Voltage refer to –Input(-Vin).

GENERAL SPECIFICATION

Efficiency: 77-85% typical, various with input.

Switching Frequency: Fixed frequency 450K Hz.

Circuit Topology: 450K Hz. Forward Circuit.

Transient Response: Max. excursion 140mV,

Recovery time <200 µSec. @ 25%

step load change.

Case: Black coated copper with non-conductive

metal base.

Operating Temperature: Industrial Grade -25°C to

+85°C range. 0°C to+70°C @ full load without derating.

From+70°C derating linearly to half load @+85°C.

(Refer to the Derating Chart for commercial grade.)

Temperature: -40°C to +105°C for industrial grade.

Temperature Coefficient: ± 0.03% /°C.

Humidity: Up to 95%RH, Non-condensing.

Cooling: Convection cooling up to+70°C @full load.

At least 100LFM moving air is recommended for

full load >+71°Cin a confined area.

Power Density: 10.0 Watts. / Cubic inch.

MTBF: 1,000,000 hours to Mil. Std. 217, 25°C.

Industrial Grade for 12B/24B/48B input.

Commercial Grade only for 5B input.

NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise specified.

(2) Line Regulation measured from High to Low Lines at full load.

(3) Load Regulation measured from Full Load to 1/2 Full Load at nominal input.

(4) Correct fuse size by calculating the max. DC current drains at low Line input & Load and then adding 20-25% for the desired fuse size.

Due to requests in market and advances in technology, specifications subject to change without notice.
