Cutler-Hammer PSS Power Supply Units feature high outrush capability, self-protecting 24V DC output and input voltage range from 120V – 480V. Power supplies are switching power supplies which meet semiconductor industry spec F47. This ensures the power supply will ride through a 50% voltage sag for 200 ms. Cutler-Hammer power supplies exceed this spec at 150% of load. Each power supply in a unit has its own disconnect switch. Additionally the D77E-PS1 power supply is specially designed for use with the D77 line of products. This power supply features universal AC input and one amp of 24V DC output to a QCPort connection for easy integration into a D77 system.
When using the D77A I/O and D77D-DNA, a simple rack and stack system can be employed by using the D77E backplanes. The backplanes have the QCPort communication and power pre terminated to a connector and comes mounted with in a DIN rail. The Backplane can be ordered in lengths of 7 slots, 12 slots and 24 slots. The 24 slot version does not come in a backplane and can be “snapped” to make any length desirable.
All IT. commencing products have QCPort connections on them that accept an Interconnect Cable. The Interconnect Cable is pre terminated with the RJ style connector and provides for power and communication on the same cable. There are multiple lengths of cables to suite many applications and mounting configurations of IT communicating products.
Each QCPort system must have a terminator, we offer two types of termination to suite the system configuration. First there is a single unit that has is a terminator only (D77E-TERRJ), this unit has QCPort RJ connections on it so it interconnects with the QCPort Interconnect Cables. The second type (D77E-QPLR) incorporates a terminator that can be enabled or disabled, a QCPort power connection, indication of power and communication and terminals for the QCPort communications. This terminator has QCPort RJ and Backplane connections on it so it can be incorporated into any QCPort system configuration.
