Máy tạo dòng điện 200A-3PH/ED
Main Output
The units have three independently controlled outputs, one for each phase. The output is switched on and off by illuminated pushbuttons, and the current is set using the three control knobs on the front panel. All ranges are continuously variable from zero.
| Range | Continuous | 5 minutes | 1 minute |
| 5V | 50A | 100A | 200A |
The above intermittent on times must be followed by an off time of 15 minutes, and are based on an ambient temperature of 25°C.
Auxiliary AC
Outputs A switched, isolated auxiliary 240V 50mA AC supply is available to power auxiliary control circuits. The output is protected by a fuse.
Digital Metering
The output on the 200A-3PH/ED is metered by a digital true RMS system with a 3.5 digit LED display. The range for each channel is independently selected for each channel by a switch on the front panel.
| Range | Resolution | Trip Current | Accuracy |
| 10A | 0.01A | 11.5A | ±0.6% rdg+6d |
| 20A | 0.01A | 23A | ±0.6% rdg+6d |
| 100A | 0.1A | 115A | ±0.6% rdg+6d |
| 200A | 0.1A | 230A | ±0.6% rdg+6d |
An electronic current trip is automatically set to 115% of full scale of the selected metering range to protect the device under test.
Supply Requirements
| 400V+14%-6% | 50/60Hz | 3ph | 4 wire | 3300VA max |
A delta-star transformer is available as an optional accessory for operation from a 3 wire supply.
Temperature Range
| Storage | -20°C to 60°C |
| Operating | 0°C to 45°C |

Timing System
The timing system on the 200A-3PH/E/ED is very flexible, allowing a wide range of protective devices to be timed.
| Range | 0-999.999s |
| Resolution | 1ms |
| Accuracy | 0.01% rdg +1d (all except current operated mode) |
| 0.01% rdg +3d (current operated mode) |
The contact circuit has an open circuit voltage of 24Vdc and a short circuit current of 300mA. The contacts may be connected to volt-free contacts or contacts connected to a DC voltage system (220Vdc maximum).
The following functions are provided:
| Mode | Timer Start | Timer Stop |
| Normally Open | Press ‘ON’ | Contact closes |
| Normally Closed | Press ‘ON’ | Contact opens |
| Current operated | Current > 20%of range | Current < 20%of range |
| Off | Timer inoperative | Timer inoperative |
The output is automatically switched off at the end of the test to safeguard the relay under test.
Protection and Safety
The 200A-3PH/ED is protected by electronic over current trips on the outputs, fuses on the contact input, the mains input and regulators.
The auxiliary AC output is fuse protected on both units. An earth terminal is provided for connection to a local earth.
The unit is designed to comply with BSEN61010, and is CE marked.
