ABB PSR16-600-70PSR16-600-70 avviatore graduale

the softstarter psr16-600-70 has a rated maximum operational current of 16 a with an operating voltage span from 208...600 v ac. the rated control voltage is between 100...240 v ac at 50/60 hz. psr features a two-phase control soft start and stop through a voltage ramp. it has built-in bypass for easy installation and energy saving. a run signal is available from a relay output in no (normally open state). the start/stop ramp and time is easy to set by three potentiometers on the front. psr is often used in combination with a manual motor starter (mms) from abb, so mechanical connection kits are available. another popular option is fieldbus communication, which can be enabled by an external adaptor and a fieldbus plug. the psr range is our most compact softstarters with basic functionality and values. they are suitable for small three-phase motors with nominal current
