5.0 POWER REQUIREMENTS
5.1 ELECTRICAL POWER CHARACTERISTICS
5.1.1 DC Power
Electrical power characteristics were determined by high fidelity testing at the Electrical Power
Systems Laboratory using a STS power bus to power a PGSC SED39126010-305 power
supply that provided the necessary operating power to the PGSC. Current was measured for
different input voltages, and readings were taken at the power source while the PGSC was
running a program that caused approximately 75-80% of the screen pixels to be turned on and
while the removable Ni-MH battery was charging. Results of the test are shown in Table 5-I.

5.1.2 AC Power
AC Electrical power characteristics were determined by connecting an AC power supply to the
PGSC Expansion Chassis Assembly. Current was measured for different input voltages, and
readings were taken while the PGSC was running a program that caused approximately 75-
80% of the screen pixels to be turned on. Results of the test are shown in Table 5-2.
