B Series & BL Series
2 - 170 Watt Single Output Power Supply

Features

Superior reliability: 626,400 hours MTBF.

High Voltage Converter (up to 500 Vdc output).

314 standard models.

Meets MIL-STD-810C.


Specifications

Input:

24 - 30 Vdc.  Other inputs available (see H option).

Output (nominal):

5 - 500 Vdc.

Efficiency:

30% - 60%.

Line Regulation:

Within 0.04% for change from low line to high line with load constant.

Pard (Noise and Ripple):

0.5% rms on model B
1.0% rms on model BL

Isolation Voltage:

200 Vdc, input to output; 200 Vdc, input to case; 200 Vdc, output to case.

Insulation Resistance:

50 Mohms between input and output, input and case, output and case, when measured at 50 Vdc.

Polarity:

Inputs and outputs are isolated. Either positive or negative side of output may be grounded.

Temperature Range:

Operating: -55°C to +100°C maximum, at center of the baseplate. Storage: -55°C to +125°C, ambient.

Input Transient Protection:

Unit will withstand 80 Vdc for 0.1 second, in accordance with MIL-STD-704A.

Reliability:

MTBF is calculated per MIL-HDBK-217C at 50°C baseplate temperature with maximum operating input voltage and maximum rated output power. The MTBF for B05D-24.7A at ground benign environment is 626,400 hours.

Environment:

Encapsulated and hermetically sealed to meet the environmental requirements of MIL-STD-810C.

Connectors:

Standard unit is provided with an input solder pin header and an output "hermetic seal" stud-type connector.

Weight (Lbs.):

0.7 - 10.3

Options

A Option:

Special Connectors. A military-type hermetically sealed connector is provided in place of our standard input header to extend out the top surface. To order, replace the "D" in the model with "A".

B Option:

Alternate Header Location. The standard multiple pin header is relocated to the baseplate surface. To order, replace the "D" in the model number with "B".

E Option:

Severe Shock, Acceleration and Vibration. Enables all units to withstand 60 g's shock, 50 g's acceleration and 30g's vibration. To order, add "E" after "D" in the model number.

H Option:

Wide Input Voltage. Recenters the input voltage to provide alternate inputs from 20 Vdc to 32 Vdc. To order, add an "H" after the "D" in the model number. Add new input voltage range in parentheses.  For input range of 22 to 32 Vdc (max. limit) a 10% derating is required.  Input range can vary between 6 Vdc without derating i.e. 26-32 Vdc, 20-26 Vdc.
