Product overview

Introduction

The RPS1600-A is an external power supply that uses AC inputs and provides eight lines of DC output, with a maximum output power of 3200 W (220 VAC input voltage) and 1600 W (110 VAC input voltage). It can provide DC power supply simultaneously for multiple powered devices (PDs), such as switches and routers. The RPS1600-A can serve as:

·     A heavy-duty external PoE power supply

·     A redundant power supply for PDs

Serving as a redundant power supply, the RPS1600-A offers the following functions:

·     If using the same AC power source with a PD, when the internal power supply system of the PD fails, the RPS1600-A can provide DC power supply to the PD, ensuring uninterrupted operation of the PD.

·     If using a different AC power source from the PD, when the AC power source to the PD fails, the RPS1600-A can provide DC power supply to the PD, ensuring uninterrupted operation of the PD.

The RPS1600-A adopts a power supply failover mechanism: when the power supply of the PD works properly, both the RPS1600-A and the PD’s power supply can supply power to implement load sharing; when the power supply of the PD fails, only the RPS1600-A works to ensure uninterrupted operation of the PD.

 

	NOTE: As optional parts for the RPS1600-A, different types DC output cables are available depending on the requirement of the powered device. For details about the DC output cables, please consult H3C marketing or customer service staff.

Table 2 Protection features of the RPS1600-A

Item	Description
Input over-voltage protection	When the input voltage exceeds 295 ± 5 VAC, the unit executes an over-voltage protection shutdown and displays an alarm through the alarm LED. When the input voltage comes down to 275 ± 5 VAC, the unit automatically recovers and clears the alarm.
Input under-voltage protection	When the input voltage comes down to 75 ± 5 VAC, the unit executes an under-voltage protection shutdown and displays an alarm through the alarm LED. When the input voltage rises to 85 ± 5 VAC, the unit automatically recovers and clears the alarm.
Output over-voltage protection	When the output voltage exceeds –59.5 VDC, the power module executes an over-voltage protection shutdown and displays an alarm through the alarm LED. To remove the fault, pull out the power module and insert it again, or turn off the AC input and turn it on again.
Output over-current protection	When the output current of a power module exceeds 31.5 ± 1.5 A, the power module executes an over-current protection shutdown and displays an alarm through the alarm LED. When the over-current condition is eliminated, the power module automatically recovers and clears the alarm.
Per-output over-current protection and short-circuit protection	A protection action of one output does not affect any other. ·     For a 25-A output, press the reset button to clear the condition; ·     For an 8-A output, check the corresponding fuse, and replace the fuse if it was blown to clear the condition.
Over-temperature protection	At temperatures between 65°C (149°F) and 75°C (167°F), the unit operates with reduced output power. At temperatures higher than 75°C (167°F), the unit executes an over-temperature protection shutdown and displays an alarm through the alarm LED. When the temperature comes down to 65°C (149°F), the unit automatically recovers and clears the alarm.
