MTE DC link chokes
MTE’s DC LINK CHOKES offer the advantage of maximizing the circuit inductance for power quality reasons, but without causing an AC input line voltage drop.
MTE’s DC LINK CHOKES, also referred to as DC line chokes or inductor chokes, are an economical means of filtering and controlling the DC bus voltage and current in a variable speed drive/inverter. They help reduce AC input line current harmonic distortion while absorbing DC bus voltage spikes. Link Chokes add protection and filtering but should not be considered a direct alternative to AC input or output reactors.
Features:
– Solid Copper Box lug type terminals on most sizes
– Specially constructed and epoxy impregnated for low noise
– Customized ratings also available—contact factory for custom mounting, inductance, current or ripple requirements
Benefits:
– Reduce AC input line harmonics
– Help meet IEEE-519 limits
– Absorb voltage/current spikes
– Reduce AC ripple on DC bus
– Reduce dv/dt and di/dt rates
– Solve nuisance over-voltage tripping
– Reduce DC Bus transient over-voltage
