The R4400 DC VSD provides pulse free constant pressure operation on any DC voltage from 10-29 volts. Operation from no flow to maximum flow is system controlled, eliminating unwanted pump cycling and the need for an accumulator tank. The system provides reduced amp draw and quite operation when less than maximum flow is required. Standard features include soft start to reduce splash, thermal overload, over-current and reverse polarity protection.

Features:

• Constant Pressure Operation
• Variable Speed Control
• Solid State Pressure Sensor
• Nearly Silent Operation / No Cycling
• Operates on 12V DC or 24V DC
• Controls Pressure by Changing Motor Speed
• Self-priming / Runs Dry Without Damage
• No Accumulator Tank Needed
• CSA Listed / EN ISO 8846 Marine / C.E. Certified
• Patent Pending
