    HVAC Building Construction Question

    Hi-- What a brotherly advise from Goorah. I like it, sensible-- experience is learning anyway but not much than learning is experience. csr

    Wierd Resistor Identifaction

    Hello-- Probably you are looking on a metal film type resistor. However, not only resistor nowadays used colorcoding like that but also coils, capacitors, fusable resistors, pack the same way as standard resistor. You din't mention the size in Watts. csr

    clean 9.6 volt DC at 5.0 amps from varying 18 to 90 VAC source

    You may need to shape up your input from a varying source voltage to a fix voltage source. Say 15 Volts AC to be exact. From then on, introduce an ac-dc voltage rectifiers rating with a forward current of 10A and a computer grade filter capacitors. Now you can have a pure DC voltage somehow with...

    AC Motors

    Hi electricpete-- I mean to say total current as per specification from 1875KVA. Would it be It=Ia=Ib=Ic? Thanks for being prompt. C.A.A.

    AC Motors

    Thanks for your confirmation cbarn,electricpete and busbar. I would rather choose to look for a whole package power monitoring device that will feed information to my program which monitors status of the loading condition of my genset. I have variable 220Volts load with respect to ground. I...

    AC Motors

    I'm trying to figure-out what would be the approximate max. or by calculation of phase currents I1,I2,I3 in a 3 phase-four wire system, with a given 1875KVA/380Vac, rated generator.(Balance load) The question is for me to determined the type of CT's to be installed in 3 phases for add/shedding...

    a chip that puzzels me

    Maybe its a house-partnumber. Accustomed by the OEM. (If you mean that even in the IC Master.) Contact the equipment OEM Website support if named.

    Fuse types for control ciruit

    Slow blow or fast acting fuses are fair enough. Fuses meant to protect the devices when excessive amount of current drawn to your circuitry beyond the calculated value or input current specification. Tolerances can be determined according to the type of application you will have, inductive...

    555 timing

    Hi, Configure your 555timer ic power supply with a common ground. Say like + or - 5Vdc for 10Vdc supply voltage to the timer so that you can achieve a +5V or -5V voltage swing near saturation.
