he Unipower HPL130A is a member of a family of "Intelligent Power Control Units". The unit measures power (kW) from the following formula: P = √3 x U x I x Cosϕ
The primary function of the unit lies in the supervision and control of machinery dri-ven by 3-phased AC-motors. The HPL130A integrates a Max. kW and a special dP/dt limit detector. The unit has been developed specifically for the super-vision of machinery that experiences va-riable power consumption because of shifting load or large temperature deviations. As well as the support functions Ts, Tr, hysteresis etc. the HPL130A has a built in current converter that works up to 8 Amp.
