KW2G / KW2G-H Eco-POWER METER18Without Ammeter3.7 For input connection●Pulse input (Main unit)・Contact inputUse highly reliable metal plated contacts. Since the contact’s bounce time leads directly to error inthe count value, use contacts with as short a bounce time as possible. In general, select 30Hz formax. counting speed.・Non-contact input (Transistor input)Connect with an open collector. Use the transistor with the following specifications. V CEO=20V min.IC =20mA min. ICBO=6μA maxUse transistors with a residual voltage of less than 2V when the transistor is ON.*Short-circuit impedance should be less than 1kΩ.(When the impedance is 0Ω, drain current is approx. 7mA.)Open-circuit impedance should be more than 100kΩ.・Input wiringPlease wire up to 10m by using a shielded wire or a metallic electric wire tube individually.⑦ ⑧P.IN + P.IN －Secondary currentBreakerPower supplyCT with 2nd current 5AKLLoadDedicated CT for 5AL KEco-POWERMETERShorted or resistor less than 0.1Ω
