Detailed Description

Internal Power Supply

AC Input:

100~240VAC, 50~60Hz

Optional Redundant
Power Supply

One connector in back to install optional external RPS. When internal power fails, the
optional external RPS will take over all the power supply immediately and automatically.

DPS-500:

DGS-3420-28SC/28TC/26SC/52T

DPS-700:

DGS-3420-28PC/52P

Fans

The IC Sensor detects the temperature on the switch automatically, and adjusts the
speed.

Power Consumption

DGS-3420-28SC: 60.3 Watts (Max.)

DGS-3420-28TC: 50.8 Watts (Max.)

DGS-3420-26SC: 60.3 Watts (Max.)
