3300 ASU and Universal ASU Power

 

Power Supply Input Specifications

Note: Connector is a Standard Male IEC320 AC input.

 

 

Voltage

Universal input design, operating input voltages from 90VAC to 264VAC.

 

It regulates a +5, -48V, -30V, -5V, 70VAC ringing signal, and the –115VAC

 

Message Waiting Signal.

 

 

Current

< 1.0A RMS at 90VAC and full rated load.

 

 

Frequency

AC input frequencies from 47Hz to 63Hz.

 

 

Holdover

With an input voltage of 120VAC or 240VAC under a full rated load, the

 

power supply outputs remain in regulation for a minimum of 16ms after loss

 

of AC mains input voltage.

Note: The 3300 Universal ASU connects to the 3300 Controller over a Category 5 Universal Twisted Pair (UTP) cross-over cable through a CIM interface. The Category 5 cable is of the same type used for Ethernet connections and within the cable twisted pairs are arranged as: 1,2: 3,6; 4,5; 7,8. Each tied pair is connected to a 75 ohm resistor. The 3300 Universal ASU can be located up to 30 meters (98.4 feet) away from the 3300 Controller. The interface employs a single standard 8-pin modular jack consisting of 2 balanced signal pairs and is located on the front of the unit.
