PSR – The compact range

Introduction

2
Motor protection with manual motor starter
Use the PSR together with the MMS to get
a complete motor starter with soft start and
stop together with overload and short circuit
protection.

Connection kit (optional)
The connection kits simplifies installation of
the PSR by making the connection to the
MMS screwless.

Screw or DIN-rail mounted
PSR is fast and easy to install by using
screw mounting or DIN-rail mounting
(PSR3 ... PSR45).

Output signal relays
PSR has output relays for Run and Top of
ramp (PSR25 ... PSR105).

LED indicators
PSR has LED indicators for On/Ready and
Run/Top of ramp.

Three potentiometers for settings
Set-up is made very easy with only three
potentiometers, for start ramp time, stop
ramp time and initial/end voltage level.

Settings

2 Step down
1 Start = 1...20 sec
1 3 U ini
2 Stop = 0...20 sec - including the step down voltage 3 U end
Step down = 2% reduction for each second increased stop ramp 2
3 U = 40...70% results in end voltage = 30...60% 3
ini
1 Start 2 Stop
