DSE Model 5220 Automatic Mains Failure & Instrumentation System Operators Manual
36 057-012 5220 OPERATING MANUAL ISSUE 5.1 18/06/2007 AM
10 SPECIFICATION
DC Supply Continuous voltage rating :
8V to 35V
Cranking dip protection :
Able to survive 0V for 50mS, providing supply was at least 10V before dropout and supply
recovers to 5V. This is achieved without the need for internal batteries
Charge Fail/ Excitation:
0V to 35V fixed power source 25W
Max. Standby Current:
375mA at 12V. 200mA at 24V.
Max. Operating Current:
460mA at 12V. 245mA at 24V
Alternator Input Range:
5V - 277(ph-N) (+20%) 50Hz - 60Hz (Minimum 15V AC Ph-N)
Accuracy:
1% of full scale Average sensing
Supported topologies:
3 Phase 4wire
Single phase 2 wire
3 phase 3 wire
2 Phase 3 wire L1 & L2
2 Phase 3 wire L1 & L3
Mains Input Range:
15V - 277(ph-N) (+20%) 50Hz - 60Hz
Accuracy:
1% of full scale Average sensing
Supported topologies:
3 Phase 4wire
Single phase 2 wire
3 phase 3 wire
2 Phase 3 wire L1 & L2
2 Phase 3 wire L1 & L3
CT’s Burden:
0.5VA
Primary rating:
1A - 6000A (user selectable)
Secondary rating:
5A secondary
Accuracy of measurement:
1% of full load rating (when using 0.5% or better CTs)
Lower class CTs will reduce the overall accuracy of the reading.
Recommendations:
Class 1 required for instrumentation
Protection class required if using for protection.
Magnetic Pickup Voltage range :
+/- 0.5V minimum (during cranking) to 70V Peak
Frequency range:
10,000 Hz (max)
Relay outputs Fuel:
16 Amp DC at supply voltage
Start:
16 Amp DC at supply voltage
Auxiliary outputs 1,2,3:
5 Amp DC at supply voltage
Dimensions Overall:
240mm x 172 mm x 57mm
(9 ½“ x 6 ¾” x 2 ¼”)
Panel cut-out:
220mm x 160mm
( 8.7” x 6.3”)
Max panel thickness 8mm ( 0.3”)
