INSULATED INVERTER FOR METRO CARS EMERGENCY VENTILATION
METRO CARS EMERGENCY
INSULATED INVERTER FOR METRO CARS EMERGENCY VENTILATION
Static inverter powered by 24V battery for driving emergency ventilation fans with asynchronous motors in metro cars.
Output voltage
feedback
control
Soft-start for motors, realized by output U/f ramp
Sine-wave
PWM
technology
Automatic restart after
a recovery from fault condition
Output short-circuit protection
Current limitation
Insulated between input and output PC-based diagnostic and setup
Floating contacts for operational status indication
INVERTER CONTROL
Inverter is started by external input signal with configurable delay. Operating point can be configured by external communication.
The operating point is defined by the output voltage and frequency.
CONSTRUCTION
Coated stainless steel case with removable lid. Connection via connectors (ILME or Harting)
The diagnostic line is attached using D-SUB9M connector
Exact specification will be agreed upon during implementation
