SCP250 1EC Compact Plate Axial Fan Single Phase EC 250mm

The Elta SCP250-1EC is a 250mm Compact SCP plate mounted axial fan with a single phase EC motor, moving up to 868 m³/h at full speed and working against static pressures up to 75 Pa. Speed is fully variable, so one fan can be set to the duty you need.The IE5 efficiency EC motor has an integrated variable speed drive, runs on 220-277V 50/60Hz and reaches 1795 rpm at 10V, drawing 58 W and 0.53 A. Speed is set by a 2-10V DC signal, 4-20mA, a PWM signal (10-95%) or a potentiometer. The Series 1 impeller has adjustable pitch GRP aerofoil blades, an IP55 terminal box is fitted on trailing leads, and Elta give a 12 month warranty. 1 Phase EC Motor Up to 868 m³/h Speed Controllable What it is best used forThrough-wall ventilation that needs variable or BMS controlled speed on a single phase supply in plant rooms, stores, small workshops, garages and back of house rooms in shops. At 868 m³/h it gives about 6 air changes an hour in a space of roughly 150 m³, for example 10m x 5m with a 3m ceiling. Turned down to 8V it still moves 673 m³/h at 40 dB(A).Its pressure (up to 75 Pa on the datasheet) is high for a plate fan, but it is still not a ducted fan for long runs; use a cased axial or inline mixed flow fan there. EC fans are rated for air up to +60°C, and it is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesAgainst the single phase AC Elta SCP250/4-1AC (954 m³/h, up to 50 Pa, 80 W, 42 dB(A)), this EC version needs no separate transformer controller and gives stepless control from a BMS signal. The three phase Elta SCP250/4-3AC gives 1188 m³/h, up to 50 Pa, 90 W, 42 dB(A). At reduced speed EC power falls sharply, which is where it saves running cost over a fixed speed AC fan.Installation notes Mount the 370 x 370mm fan plate securely at any angle using the four 10mm holes on 320mm centres, and leave access for maintenance. Supply is 220-277V single phase 50/60Hz. Wire to Elta diagram 152-711. The fitted 149-CD-POT commissioning trimmer sets the maximum speed; remove its jumper when using an external 149-POT-10-MI potentiometer, 2-10V, 4-20mA or PWM signal. Keep control cables within Elta's limits: 10m for a voltage or PWM signal, 300m for 4-20mA. Allow at least 5 minutes between starts from the mains supply, and do not use the isolator for day to day control. High voltage can remain in the motor for up to 10 minutes after isolation. At first start check rotation and airflow direction. Inspect and clean blades and guards at least every 12 months. You'll also need Elta EC electronic controller 149-POT-10-MI for manual speed control.
