SPECIFICATIONS
1.1 Output
Ratings
1.1.1 Voltage: Nominal -48 volts DC, positive ground, non-adjustable.
1.1.2 Current:
10 amperes per DC-DC Converter Module, up to a total of 30 amperes per DC-DC
Converter Mounting Shelf when three (3) Converter Modules are installed.
1.1.3 Regulation
(A) Static: Steady state output voltage remains within ±1 volt of the pre-adjusted voltage for
any load current from no load to full load and over the specified input voltage range.
(B) Dynamic:
For a step load change of 50% within the range of 10% to 100% of full rated
current, the maximum voltage transient will not exceed 5% of the initial steady state voltage.
1.1.4 Filtering:
With at least 10% of rated full load on the output (-20°C to +65°C).
(A)
Voice band noise is less than 32 dBrnC when measured with a noise meter using 600 ohm
bridged input and C-message weighting.
bridged input and C-message weighting.
(B)
Wide band noise does not exceed 250 millivolts peak to peak over the frequency range of 0
Hz to 20 MHz.
Hz to 20 MHz.
(C)
Wide band noise does not exceed 30 millivolts rms over the frequency range of 0 Hz to 20
MHz (as measured with an HP3400A true rms voltmeter).
MHz (as measured with an HP3400A true rms voltmeter).
(D)
Noise below –20°C is slightly higher.
1.1.5 Output
Distribution:
Two (2) 6-Position GMT Fuse Modules are provided for connecting DC
output load leads.
