ELECTRICAL CHARACTERISTICS
• Supply voltage: 12 Vdc (11 to 15 volts)
• Output current (uni-polar): maximum 160 mA with a 22
ohm load
• Adjustments (see Adjustments):
1.OFFSET sets start current (threshold)
2.MAX sets maximum current output
3.GAIN sets current output with respect to foot pedal
position
All adjustments are clockwise (< 1 turn) for increasing.
To access the adjustments, remove the 4 cover screws.
• Input impedence: 200K ohm
• EMI/RFI protection
This amplifier is designed to work with the Danfoss foot pedal (KEP). A typical application would be controlling a
variable volume piston pump that is fitted with an Electrical Displacement Control (EDC). Trim pots on the amplifier allow the
output levels to be tailored with respect to foot pedal position. An enclosure protects the internal circuit board and provides
a means of mounting. The control has (3) LEDs to indicate +12 V power, +8 V regulator and output current.

Controlling a Single Coil EDC Requires a Double Pole,
Double Throw (DPDT) Switch for Changing Direction.
Controlling a Dual Coil EDC Requires a Single Pole,
Double Throw (SPDT) Switch for Changing Direction.
Also, Just One Coil of a Dual Coil can be Wired and
Switched as in Above Diagram.
When Controlling Two or Three EDCs, They must be
Wired Coils in Series/EDCs in Parallel as Shown in Diagram
Below. A Double Pole, Double Throw (DPDT) Switch is
Used for Changing Flow Direction of the PV.
