Control Systems

Dual D / A Local / Remote Electric Start Controller

Model: DMES 170
 
Similar to the model MES 170 and incorporates all the features of that controller but includes extra facilities to allow two sets to be monitored and protected. The application of this controller is where a property generates its own power and has two sets, only one of which is required to run at any one time.

This allows:

• A set to be taken off line and serviced.
• A set to be held as a manual standby set.
• A smaller set to run during light load periods.

Offered for 3Ø machines up to 22kW or 1Ø machines to 12kW in both 12 and 24Vdc versions. Larger machines can be accommodated through the use of a separate load switching cubicle.

Features

All the features of the MES 170 unit.

• Integral static constant potential current limited battery charger.
• Load connection contactors for each set.
• Set control selector switch.
• Metering load current transformers.
• Delayed contactor closing to ensure correct speed and voltage is attained.

Leading Characteristics

• Same as the MES 170 model but including:
• Dual 6 digit engine service hours counters.
• Input capacity:
• 3f 22kW  28kVA   40A
• 1f 12kW  15kVA   62.5A
• Two position set selector switch. One phase load ammeter with selector switch on 3Ø versions.
• Controller  weight   41kg
