Power supply
The 120 pump is suitable for single-phase mains electricity supplies only via the double-insulated (Class II)
90– 264VAC to 24VDC mains adaptor. Use only the approved 24VDC Meanwell type GE24I24-P1JK DC
adaptor or thePowersolve ESA24-24DC adaptor supplied with thepump.
A well regulated electrical mains supply is required along with cable connections conforming to the best
practice of noise immunity. It is not recommended to site these drives alongside “dirty” electrical mains
supplies such as 3-phase contactors and inductive heaters without special attention being paid to
unacceptable mains-borne noise.
