2.4.6 DC Power Configuration & Wiring
The ControlWaveLP requires a DC power source within the range of +10.6 to +30 V. A DC
to DC Converter on the Power Supply Sequencer Board (PSSB) generates isolated +5VDC,
+12VDC & -12VDC. A sequencer circuit monitors the external supply and the +5V, +12V
and -12V supplies, and an analog to digital converter (ADC) measures the external voltage.
The power supply operates from 10.6 to 30 VDC. The nominal settings for the supply are
ON state above 11.1V or 22V, OFF state below 10.6V or 20.7V. A power MOSFET switches
the bulk input power to the power supply. The isolated supplies are rated for 5V (VCC) @
1A, +12V @ 200mA and -12V @ 200mA. Linear regulators regulate the +/- 12V supplies
while the 5V supply (VCC) is regulated by the PWM circuitry. The PWM IC will shutdown
when the incoming power drops below 10.6V or 20.7V.
PSSB Board connector TB2 provides three terminals for power and ground as follows:
TB2-1 = 10.6-30VDC input - (V+)
TB2-2 = PSGND (Power Supply Ground) - (V-)
TB2-3 - CHASSIS (Chassis Ground) - (
)
DC Power is interconnected to the ControlWaveLP system via PSSB Connector J1 and
FMI/OB Connector P9 (see Table 2-12).
