Redundant source guarantees Ethernet power

A novel redundant power source features up to 180 power-over-Ethernet ports to meet the needs of telecomms applications such as VoIP systems

Phihong has developed a redundant power source with up to 180 power-over-Ethernet ports to meet the needs of telecomms applications such as VoIP systems. The RPS accepts three 500W power supplies for powering VoIP phones, DC UPS, and lighting systems with single UPS. A typical VoIP phone draws less than 8W.
With 1500W available, 180 PoE phones can be supported from this redundant source.

'Redundant power sources are essential to VoIP systems, particularly for businesses where downtime due to power failure can significantly compromise operations', said Keith Hopwood, Vice President of Marketing for Phihong USA.

'If VoIP power is provided by PoE devices, an RPS is necessary to keep power generating during an outage'.

Each output in the redundant power source is individually protected against overloads causing overheating of wiring from excessive current, thus fully protecting the system against overload, overtemperature and over-voltage.

It features diagnostic capabilities and LEDs next to each connector.

The RPS was designed to allow easy connection of a battery plant for full DC UPS capability for VoIP phone systems or network switches.

A single battery plant can provide a UPS function for over 180 IP phones or a complete rack of network switches.

The redundant power source measures 438 x 350 x 44.5mm, and it weighs 1.1kg.

OEM pricing for the PSM1500 Series RPS with one 500W supply is $189.

Lead time is from stock to 10 weeks.
