IMA315 - PORTABLE 3-PHASE POWER TEST SIMULATOR

IMA315 is a 3-phase current simulator in the Megacon range of transportable test equipment.

 

This unit is designed for general testing of Megacon’s or other brands range of protective guards and controllers for generator and power plant automation systems (current, current  differential, overcurrent and short circuit, active (kW) and reactive (VAr) power  etc).

 

IMA315 has multiple input supply voltage range from 100VAC and up to 690VAC and individual current output, 0-3A & 0-15A for each phase (R - S - T).

• The phase sequence indicator shows that current outputs have correct sequence. If LED’s shows INCORRECT, please change your input wiring

• All current outputs are galvanically isolated from the mains supply

• IMA315 Unit have a cos phi factor of app. 0,75

Phase Sequence

IMA315 is fitted with a phase-sequence indicator. Correct phase sequence is a precondition for measurement of active power and reactive power.   

Outputs
Each output current terminal's phase reference (R-S-T) and the direction of current flow (K: supply, L: load) is clearly marked.

However, it the input sequence is for example S-T-R, you have the correct phase sequence but output current will also come out in the same sequence  S-T-R.

The current outputs are individually adjustable 0-3A or 0-15A (selectable on selector switch)

Variable Current Output
The maximum current to be drawn from any of the current outputs largely depends on the ohmic resistance of the external current loop. The current terminals are rated 20A, and 4mm plugs may be flipped into the center of the terminal.

Use large size wires for high current levels to reduce ohmic losses. (Recommended wire is minimum 2.5mm²)

Transit / Storage Container
IMA315 is built into a solid Pelicase suitcase P1560M with integrated wheels and handle for easy carriage and safe transport handling.

MKR51 - PORTABLE SINGLE PHASE POWER TEST SIMULATOR

For testing of generator guards and protection units

MKR51 is a portable single-phase current simulator in the Megacon range of transportable test equipment. It is a handy tool for general testing of Megacon’s or other brands range of protective guards and controllers (current, current  differential, overcurrent and short circuit, active (kW) and reactive (VAr) power etc).

Intputs
MKR51 has multiple input supply voltage range from 100VAC and up to 690VAC and 2 current outputs, 0-3A & 0-15A with a cos phi factor of 0,71.

Variable Current Output
The maximum current to be drawn from any of the current outputs largely depends on the ohmic resistance of the external current loop. The current terminals are rated 20A, and 4mm plugs may be flipped into the center of the terminal. Use large size wires for high current levels to reduce ohmic losses. (Recommended wire is minimum 2.5mm²)

Fuses
Ceramic fuses on unit front protect the internal voltage transformers.

Transit / Storage Container
MKR51 is built into a solid Pelicase suitcase 1500 for easy carriage and safe transport handling.

IMA95 - Power Test Simulator

IMA95 is one in a range of Megacon's transportable test simulators. This unit is specifically designed for testing of Megacon's or other brands range of protective guards, controllers and regulators for marine generator and power plant automation systems (current, current differential, overcurrent and short circuit, active (kW) and reactive (VAr) power, power overload, reverse power, load sharing, voltage, earth fault etc).

IMA95 is used for general testing and calibration of AC ammeters and voltmeters, watt-, VAr- and cos phi-meters, measuring converters (transducers) for AC current, AC voltage, single phase or three phase 3-wire balanced and unbalanced active (W) and reactive power (VAr), energy (Wh), power factor, etc.

IMA95 has input over-voltage protection. Its phase sequence monitor verifies that all voltage and current outputs have correct R-S-T sequence, configuration and phase relationship. All current outputs are galvanically isolated from the mains supply. Voltage outputs are NOT isolated from the mains supply.

 

3- and 4-wire isolated outputs are optionally available, using POTENTIAL ISOLATOR IMA133.

• Three phase line voltage input:
  200-240V and 380-460V, 50/60Hz (115V and 690V optional with the IMA133 transformer)
  
  

• Three phase current outputs:
  Individually adjustable 0-15A (depending on setting of the adjustable voltage knob)
  
  

• 3-wire line voltage outputs (All values given for zero load):
  Variable 0-250V or 250-500V range
  Maximum output voltage depends on the input voltage:
  Example 1: I/P: 220V or 440V gives app. range of 0-265V and 225-485V output
  Example 2: I/P: 380V gives app. range of 0-225V and 190-417V
  
  Fixed 230 and 440V output. (Also depending on input voltage)
  For input range 200-240V the fixed outputs will be: 230V = I/P  x 1, 440V = I/P x 2
  
  For input range 380-460V the fixed outputs will be: 440V = I/P : 1, 230V = I/P : 2
  Example 1: I/P: 220V gives fixed 220V and 440V output
  Example 2: I/P: 400V gives fixed 200V and 400V output
