MIL-E-50739(MU)

8 August 1973

REQUIREMENTS

3.1 Fabrication. The electronic component assembly, herein

referred to as the assembly, shall be manufactured in accordance with

Drawing F11738818 and drawings pertaining thereto.

3.2 General specification. The assembly shall meet the follow-

ing requirements, where applicable, of MIL-F-13926:

a. Order of precedence

b. Dimensions and tolerances

c. Part ldentification and marking

d. Electrical and electronic assemblies

Workmanship

3.2.1 Soldering. Soldering shall be in accordance with MIL-S-

45743 or MIL-S-46844, except that bare copper wire exposure shall be

permitted at clipped ends of component leads.

3.3 Performance. Unless otherwise specified, the assembly

shall meet the performance requirements of this specification at standard

ambient temperatures between 60 degrees Fahrenheit (F) and 90F.

3.3.1 Loads, power, signal, and interconnections. The assembly

shall perform as specified herein when the loads, power, signal, and inter-

connections of table I are applied as specified.

3.3.1.1 Low/high battery voltage charge current. With the power

source (item 2.1) of table I applied to P1-24 and adjusted to +24.0

2.0 Volts direct current (Vdc), and with the load (item 1.1) of table I

connected, the current flowing through the specified load shall be 200 +80

milliamperes (mA). With the load (item 1.1) of table I disconnected and

with the load (item 1.2) of table I connected, the current flowing through

the specified load shall be 200 8O mA.

3.3.1.2 Charger voltage regulation. With the power source (item

2.1) of table I applied to F1-24 and adjusted to +24.0 2.0 Vdc, and with

the load (item 1.3) of table I connected as specified. the voltage of P1-4

shall be +43.O 4.0 Vdc. With the above conditions existing and with

P1-15 connected to P1-16, the voltage of P1-4 shall be +36.0 3.0 Vdc.
