3.3 TERMINAL SPECIFICATION
Connection type
Two part connector.
•
Male part fitted to module
•
Female part supplied in module
packing case - Screw terminal,
rising clamp, no internal spring.
Example showing cable entry and screw
terminals of a 10 way connector
Minimum cable size 0.5mm² (AWG 24)
Maximum cable size 2.5mm² (AWG 10)
NOTE : For purchasing additional connector plugs from DSE, please see the section entitled
Maintenance, Spares, Repair and Servicing elsewhere in this document.
3.4 POWER SUPPLY REQUIREMENTS
Minimum supply voltage
8V continuous
Cranking dropouts Able to survive 0V for 50mS providing the supply was at least 10V before the
dropout and recovers to 5V afterwards.
This is more than sufficient to allow the module to operate during engine
cranking where the battery supply often falls as low as 4V (on a 12V system!)
This is achieved without the need for internal batteries or other external
requirements.
Maximum supply voltage 35V continuous (60V protection for surges)
Reverse polarity protection -35V continuous
Maximum operating current DSE7200 / DSE7300
160mA at 24V
340mA at 12V
Maximum standby current DSE7200 / DSE7300
80mA at 24V
160mA at 12V
