• V-Switch™ Key technology - field upgradeable without removing installed MP200
unit.
• Alarm and Control - used to control load or alarm when over-load or other pro-
grammed conditions exist.
• Digital Inputs - designed to count pulses from other units, such as gas, water, and
condensate.
Optional Display
The MP200 unit offers an optional touch-screen color LED display. The display is avail-
able in two sizes: 3.5” (MDSN) and 5.7” (MDLN). The display lets you view readings
from all of the meters on the MP200 unit. See Chapter 10 for MDLN/MDSN display
details.
2.1.1: Voltage and Current Inputs
Universal Voltage Inputs
Voltage inputs allow measurement up to Nominal 480 V AC (Phase to Reference) and
600 V AC (Phase to Phase). The MP200 unit will perform to specification when directly
connected to 69 volt, 120 volt, 230 volt, 277 volt, and 347 volt power systems.
Higher voltages require the use of potential transformers (PTs). The MP200 unit is
programmable to any PT ratio needed.
Current Inputs
The MP200 unit can be ordered with either a 5 A or a 1 A secondary for current mea-
surements. Depending on the MP200 metering system model, there are either 8 three
phase current inputs, or 24 single phase current inputs. The current inputs are only to
be connected to external current transformers that are approved or certified.
The 5 A or 1 A secondary is an ordering option and as such it cannot be changed in
the field. The 5 A secondary model (-10) allows the unit to over-range to 10 A per
current circuit. The 1 A secondary model allows the unit to over-range to 2 A per cur-
rent circuit.
