EL1 3 Phase
EXTERNAL THREE (3Ø) ADAPTER
The EL1 is a three phase (3Ø) adapter that takes 28 VDC input voltage and generates three phase output signals. The three phase output signals interface with three KGS static inverters, noted below, to form three phase WYE or DELTA output configuration.
The KGS models are SPC-5(G), SPC-10(L), SPC-10(J), SPC-10(U), SPC-10(F), SPC-10(N), SPC-10(H), SPC-38( ) and SPC-75(B).
The current drain from the 28 VDC buss is 25 milliamperes when the three phase output signals of the EL1 are connected to sync lines of the three static inverters.
The EL1 provides two sets of three phase signals for two groups of KGS static inverters; Group #1 - SPC-5(G), SPC-38( ) and SPC-75(B), and Group #2 - SPC-10(F), SPC-10(N), SPC-10(H), SPC-10(J) and SPC-10(U).
Group #1 inverters take a 400 Hz 15 volt square wave from the EL1 to the inverter sync lines and Group #2 inverters take a string of two level 800 Hz pulse signals from the EL1 to the inverter sync lines.
A state of the art digital design technique enables the EL1 to provide highly stable phase locking signals to the inverters generating a three phase system which delivers low distortion 115 VAC or 26 VAC and accurate phase separation.
