JUMPER CONNECTIONS FOR VARIOUS AC SUPPLY VOLTAGES

POWER

PLUG

EXAMPLE- Transformer jumpers set for 120VAC operation

AC line input voltage conversion requires reconfiguration of the power supply's AC transformer:

4-1d) OPEN FRAME POWER SUPPLY

The 1200 series console uses a bipolar (positive and negative DC) “International Series” open frame

supply built for Arrakis by Power One Inc.

The supply is adjustable from roughly ±10 to ±17 VDC.

Protection is provided in the form of current limiting-foldback. Load regulation is

± .05% for 50% load

change. Ripple is 5mv peak to peak maximum. Transient response is 50ms to a 50% load change.

SAFETY SPECIFICATIONS

Power One literature shows they meet or exceed safety requirements for IEC380, IEC435, VDE 0730

Part 2, VDE 0804, ECMA-47,

CEE 10 Part 2P, UL1012, CSA22.2 No. 143, CSA 22.2 No. 154.

Specifically, leakage current is less than 5 milliamps. Dielectric withstand

is 3750VAC input to chassis

and input to output with 300 VDC output to chassis.

4-1e) 110VAC to 220VAC CONVERSION

The power supply can be operated on a variety of AC line voltages. The supply is set up for 120VAC

operation as shipped from operation as

shipped from the factory unless otherwise requested. The supply will run on

frequencies from 47 to 63 Hz

and voltage variations of +10% to -13%.

Conversion to different

line voltages is accomplished by moving jumpers on the power supply.

FOR 120VAC OPERATION - APPLY AC TO PINS1 AND 4

Jumper pins1 to 3 and pins2 to 4

FOR 220VAC OPERATION - APPLY AC TO PINS1 AND 5

Jumper pin 2 to pin 3

FOR 230VAC OPERATION - APPLY AC TO PINS 1 AND 4

Jumper pin 2 to pin 3
