1. Grid voltage: 220V/380V/460V/660V±20%.
2. Grid frequency: 45Hz~65Hz.
Two. control
1. Braking mode: differential control based on DC bus voltage detection.
2. Action time: ≤1mS
3. Action voltage setting: factory setting or 5 gear jumper modification (economical); The operating voltage can be set arbitrarily by the keyboard (standard type).
4. Operating voltage range: 200V model: 300~380V; 400V model: 600~760V ; 660V model: 990~1155V.
5. Voltage back: 200V model: ≤10V; 400V model: ≤15V; 660V model: ≤20V.
6. Heat dissipation mode: natural convection cooling or forced air cooling, depending on the model.
7. Protection function: overheating, overcurrent, short circuit, etc.
8. Overheating action: overheating protection action when the radiator in the machine reaches 80°C.
Three. interface
1. Communication interface: RS485 communication interface, compatible with Modbus RTU protocol mode.
2. Parallel interface: four-wire master-slave parallel interface.
3. Master-slave setting: three-pin jumper setting on the board.
4. Fault output: 250V/3A normally open/normally closed contact output (depending on random type).
5. Status indication: power supply, braking, alarm indication (economical); Monitoring, Parameter, Ready, Braking, Alarm, Lock Indication (Standard).
6. Monitoring: display the current DC bus voltage and radiator temperature (standard type only).
7. Environment: installation site: indoor, altitude < 1000m, no direct sunlight, no conductive dust and corrosive gas.
