Description:
The APS SixPac™ Series of power controllers are built on a rugged, compact, all-inclusive, economical base. They have a great deal of flexibility to provide a fully functional set of power stages. They have been designed for long life in heavy-duty industrial applications. The SixPac™ CAP-AC1 includes three dual isolated SCR modules that can are configured for a three-phase AC Controller (AC in, phase-controlled AC out). These converters are ideal for any power application that needs phase controlled AC including solid-state motor starters, soft-start/soft-stop, variable speed drives, windmill alternator converters and regulated power supplies to name a few.
The isolated SCR modules are mounted on a high efficiency heatsink with optional fusing, forced air cooling, snubbers and freewheeling diode. The snubber for the SCRs is suggested if dv/dt limiting is required. The compact design measures 11.75 x 8.70 x 8.16” including the cooling fan.
The SixPac™ is available with operate with inputs from 10VAC to 700VAC, and is optimized for 220 / 480 / 575 VAC input ranges and 50/60Hz or 400Hz Input frequencies without tuning (this means that input from variable frequency alternators is acceptable as long as the frequency is within limits). AC Controller output currents range from 50ARMS to over 200ARMS. For higher current levels see the CAP-AC2 models capable of 200~800ARMS.
All units are integrated with our our industry proven three-phase SCR controller. Utilizing advanced FPGA control logic to increase reliability, circuit flexibility and reduce circuit component count, our controller board is designed to keep the programmed phase delay angle constant over a wide input frequency range (40Hz to 80Hz). This universal input feature does not require tuning in applications where the input mains frequency may vary, as in motor generator sets, windmill power generating equipment, and all field generating systems. The three-phase mains input is filtered by a unique signaling processing circuit that is not sensitive to harmonic distortion, input voltage amplitude fluctuations, frequency variations or phase sequence.
