Data sheet Fan speed controller Type Saginomiya Fan speed controller stabilizes condensing pressure by changing condenser s fan speed. The controller reduces fan noise and saves energy in low ambient conditions. Widespread usage in refrigeration and air conditioning units. Extensive performance testing under different conditions and strict quality control procedures ensure trouble free operation for many years. Compact size, reduced weight and high degree of protection means that it can be mounted directly on refrigeration lines. Panel mounting also possible. Easy adjusting made by the turn of a screw situated on the top surface. Specially designed heat dissipation radiator ensures no overheating and extended lifetime. version for EC fan motors. Features Wide regulating Compact design Male or female pressure Easy and adjusting Simple and easy electrical Cut off type or Minimum speed type Fitted with an electro-magnetic suppression filter DCS (az) 208.03 DKRCC.PD.LC0.A2.02

When pressure is declining the controller decreases the output voltage changing the speed of AC/EC fan motor. The proportional is a non-adjustable pressure difference between max. and min. pressure where the regulation occurs. For min. pressure the controller can either operates with min. speed or completely cuts off the output voltage, depending on the type of the controller. saves energy and reduces noise by lowering the fan speed or cutting it off.

The direction to turn the screw for decrease or increase in the pressure is indicated by arrow markings next to the adjusting screw. Series 360 = turn -2-4 -6 approx. 0.8bar /.6 psi approx..5 bar / 22 psi approx. 2.5 bar / 36 psi Series 360 = turn -2SE -4SE -6SE approx. 0.8bar /.6 psi approx..5 bar / 22 psi approx. 2.5 bar / 36 psi Every turn of the adjusting screw corresponds to a specified change in the value. A punch hole on the adjusting screw helps keep track of the of turns made. Installation The is designed to be directly mounted onto the refrigeration line making the most of free space in a unit. In cases where space is even more limited, can be fixed onto a simple bracket (supplied as an accessory) and screwed to a panel.
