Power and electrical considerations
The C-Series pump has the following power requirements:
• Input voltage: 24 VDC ± 10%.
• Input current; 1.5 A peak current max., 650 mA average (RMS) current
max., and 100 mA typical idle current.
Power supply requirement for single pump
The 24V DC supply for a single C-Series pump should meet the following
requirements:
• Output voltage: 24V nominal ±10% with good regulation
• Conformance to required safety and EMI/RFI specifications
• If switching supply, minimum load specification less than pump idle cur-
rent (above)
Power supply sizing for multiple pumps
When operating more than one C-Series pump, the power supply should
be sized to provide the total peak current for all devices. If pumps are
not operating simultaneously, a power supply with a reduced rating may
be used. The minimum power supply rating should be confirmed by
measurement.
It is suggested that an appropriately designed commercial power supply
be used. When using a switching power supply, make sure it has a mini-
mum load specification that is less than the total minimum current draw
(idle current, above) from the pumps.
Cabling
To reduce voltage drops and increase noise immunity, it is good practice
to use one power cable for every two pumps. Power lines to the pump
should be 24 AWG or heavier, and as short as possible, based on the
total current through the wires. Multiple C-Series pumps can be daisy-
chained, provided that the wire size and the power supply are adequate
for the total current and voltage drop. It is good practice to twist
together each pair that connects directly from a power supply to a
pump.
Switches should not be located in line with the DC input of the pumps to
apply and remove power. This can result in damage to the equipment.
