Feature

Grocery :

115*/230 Vac 50/60Hz 2 poles + earth without restriction on the test current . (*) at 115V the output voltages are divided by 2— Pmax 1200VA

Protections:

By resettable circuit breaker on the front + electronic control

General power supply and generator via circuit breakers

Generators:

A single generator usable as a current or variable voltage generator with an output on 4 ratings suitable for relays with or without auxiliary power supply .

• 0-3A, 0-6A, 0-12A with fine adjustment 0-20A without fine adjustment
• 15A maximum voltage 24V; 32A 140s
• 30A maximum voltage 12V; 100A 15s
• 70A maximum voltage 5V; 300A 15s
• 0-250Vac/2.3A permanent

Digital Mesurement Module

The control module allows the recording of time, threshold and TC report measurements in a FLASH memory internal to the device. This data can be repatriated and consulted subsequently on a PC equipped with Windows®. Computer connections are provided by USB.

Delivery Status Of The Device:

• 1 user guide (paper version)
• 1 power cord L=2.5m
• 1 reduction pin 6mm to 4mm

In Options

• Software
• Cable set

Specifications

For all three models: BASE, EVO and PRO

• 2 ranges 0-30 A and 30-300 A with automatic switching
• Accuracy: 1%
• Effective true TRMS measurement

Stopwatch

• Two internal and external on/off timer inputs
• triggering on dry contact or AC/DC voltage 1 2 to 250 V
• accuracy: 0.02% +-1ms
• measuring range: 9999.999

EVO model (has BASE functions)

This version also has an ammeter input and a voltmeter input.

The ammeter input can be synchronized with the internal generator to measure the ratio and direction of the current transformers.

The voltmeter input can be used to measure voltages generated by the MG 40 MkII or measure the load of a current transformer.

External ammeter:

• 2 ranges 0-1 A and 1-10 A with automatic switching
• Accuracy: 0.5%
• True RMS measurement—AC coupling only

External voltmeter:

• 2 ranges 0-150 Vac/dc and 150-500Vac/dc with automatic switching
• Accuracy: 0.5%
• True RMS measurement for AC coupling
• Average voltage measurement for DC coupling

PRO model (has EVO and BASE functions)

In the PRO model, an AC auxiliary power supply + a DC auxiliary power supply, a variable DC power output and a contact with high breaking capacity synchronized with the injection are available on the front.

AC auxiliary power:

• 4 fixed outputs 25V, 57V, 100V, 230V with frequency identical to the general power supply
• Front switch
• Power 20VA Protection by internal resettable fuse
• Typical uses of the output: supply of AC auxiliary sources, polarization for directional overcurrent or residual power protection tests (Example PWH)

DC auxiliary power supply:

• 4 fixed stabilized outputs 24V, 48V, 110V, 220V DC – Front switch
• Power 25W—Protection by internal resettable fuse
• Typical output uses: supplying DC auxiliary sources, contact biasing

DC variable auxiliary source:

• 1 filtered rectified output adjustable from 0-250 Vdc protected by internal resettable fuse
• Permanent power 500W—The output accepts current peaks to excite the coils of
• Typical use of the output: measurement of circuit breaker coil on/off thresholds

Synchronized power contact:

• switching 250Vac/dc 5A maximum Contact protected by fuse on the front, replaceable by the user
• NO and NC positions available
• Contact can be delayed from injection by 10 to 9999ms
• Typical use: measuring response times of circuit breaker coils in conjunction with the DC variable output. The coil voltage can be emitted or cut instantly in order to overcome rise times due to source filtering.
