Feature 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
For hardware version A1/A2, the following applies:
DGS-3420-28SC: 60.3 Watts (Max.)
DGS-3420-28TC: 50.8 Watts (Max.)
