Automatic compensation for supply variations is effective in the voltage range from 10 to 10 of the nominal voltage of the controller Control with compensation of mains variations enables constant output power to be maintained for a constant load despite variations in supply voltage Without compensation for supply variations a reduction for example of 10 in supply voltage would result in a reduction of 20 in load power This variation is less than 2 in the TE10A controller 22 TE10A PA User manual CURRENT DERATING le 4 20 25 30 35 40 45 SO 55 60 Operating temperature C Current derating curves as a function of ambient temperature IN nominal current at 45 C Dotted line limit of recommended fuse With Current limit option load current may not exceed around 110 of nominal current of controller TE1OA PA User manual 23 EUROTHERM CONTROLS LIMITED UK SALES OFFICE Eurotherm Controls Limited Faraday Close Durrington W orthing W est Sussex BN 13 3PL Telephone Sales 01903 695888 Technical 01903 695777 Service 01903 695444 Fax 01903 695666 Sales and support in over 30 countries worldwide For countries not listed overleaf enquiries orders to Eurotherm Controls Limited Export Dept Faraday Close Durrington Worthing W est Sussex BN 13 3PL Telephone 01903 268500 Fax 01903 265982 Telex 87114 EUROWG G
