A: Within each RFBE, RFFE, in each PSU Inverter, at either end of the PSU heat sink, DSP module and Ref
Gen + Aux module.
Q: If the temperature within an inverter goes too high, will the inverter automatically shutdown?
A: Yes
Q: What temperature sensor or sensors drive the fan speeds?
A: The fans' speed is dependent on the hottest module (RFBE or DSP) in their corresponding corner.
Q: Does the DSP, CSC and Ref Gen + Aux modules have temperature-sensing capability?
A: All modules except the CSC have temperature sensors.
Q: Is there there a minimum temperature consideration that is measured and alarmed?
A: No, however low temperatures can be measured and if required could be alarmed past pre-determined limits.
As the unit when on will be generating a certain amount of heat and the operational temperature range exceeds
30 deg C it is very unlikely a functional unit will go below a minimum temperature.
Q: What thermal protection is provided to the PSU?
A: There is a thermal shut down capability within each rail voltage inverter within the PSU.
AC Mains Power Supply
Front mounted AC circuit breaker.
Q: Is there a specific alarm raised when the front mounted resettable AC Circuit breaker is tripped?
A: Yes, this would trigger a major fault alarm as the AC mains power would be disconnected.
Q: What would the maximum current draw be when powering the DSPbR from a 110V AC power source?
A: 14 Amps fully loaded and operating at max power (no internal combiner) on all channels.
Q: What would the maximum current draw be when powering the DSPbR from a 240V AC power source?
A: 7 Amps fully loaded and operating at max power (no internal combiner) on all channels.
Q: What is the part number and length of the recommended 110VAC mains cord?
A: AP9872, 8.2-Ft (2.5 meter) AC Power Cord IEC 320 C19 to NEMA 5-15P
Q: What is the part number and length of the recommended 240VAC mains cord?
A: K3744-315 3.0 metre 2.5 x 1.50mm
2
Black15 Amp.
Note: The Mains power cord is commonly referred to as an IEC320-C19 Power cord.
Q: Is a special wall mount socket required for the 240VAC mains cord to plug into?
