ComNet Power Supplies

The ComNet™ C3 is a 1 RU (1.75”) high 19-inch rack-mountable card cage unit capable of mounting up to three ComNet ComFit 1.0-inch wide modules. Ideally suited to those applications where rack space may be limited, the C3 may also be used in desk-top installations by the addition of user-installed rubber feet on the bottom of the cage and removal of the two rack-mount adapter brackets. Available in either a black anodised or satin silver finish, the C3 is provided with one external 120-240 VAC power supply with a 12VDC at 2A output, and includes reverse polarity protection.

The C2 incorporates two C1PS Power Supply units that provide redundancy in the unlikely event of a power supply failure. Two AC line cords (one per power supply module) are provided, allowing each supply to be connected to a separate uninterruptible power supply, providing the highest level of reliability in mission-critical applications. An audio alarm provides an aural indication in the event that one of two power supply modules has failed. The design approach employed by ComNet for equipment mounted within the model C2 chassis rack unit with two modular C1PS power supplies, provides for the elimination of a single-point failure in the event of a major fault within any module located within the chassis rack.

ComNet™ model PS48VDC-5A is a high-quality, low-noise switching mode power supply ideally suited to those applications requiring POE (Power Over Ethernet). This rugged unit may be either DIN-rail or shelf-mounted, providing an identical mounting configuration to the mating POE switch. Up to 10 POE field devices may be powered from a single supply, and the high output current capacity provides an adequate safety margin.

ComNet™ model PS48VDC-10A is a high-quality, low noise switching mode power supply ideally suited to those applications requiring POE (Power Over Ethernet). This rugged unit may be either DIN-rail or shelf-mounted, providing an identical mounting configuration to the mating POE switch. Up to 24 POE field devices may be powered from a single supply, and the high output current capacity provides an adequate safety margin.

The design approach employed by ComNet™ for equipment mounted within the card cage rack unit (C1-CH) with modular power supply (C1PS), provides for the elimination of a single-point failure in the event of a major fault within any module located within the chassis rack. 14 1-inch rack slots available. 

The ComNet™ PS24-1A-DIN Rail Power Supply is the low profile solution for building automation. The PS24- 1A-DIN is an environmentally hardened unit which is double insulated and ideal for most installations. Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment operating status.

The ComNet™ PS12DC-HT power transformer supplies 12V DC power to ComNet™ stand-alone units. The PS12DC-HT operates on 100-240 VAC. The PS12DCHT is provided for installations with high ambient temperatures.

The ComNet™ PS12DC-1A-UNI has a removable pin head to allow it to use one of four different outlet configured pin heads to supply 12V DC power to ComNet stand-alone units. The PSU can also accept a standard figure 8 line cord input. Pin heads for the UK and Europe will be included as standard.

The design approach employed by ComNet™ for the modular C1PS power supply, provides for the elimination of a single-point failure in the event of a major fault within any module located within the chassis rack. This is accomplished through the use of automatic electronic current limiting within each rack-mountable module, rather than providing the current limiting within the power supply unit which supports the power requirements for equipment located within the rack. The C1PS rack power supply design employed by ComNet eliminates this possibility, as only the faulty module shuts down, and the operation of the other modules within the rack continue unimpaired.

The ComNet™ PS-9VDC power transformer supplies 9V DC power to ComNet stand-alone units. The PS-9VDC operates on 100-240 VAC. The PS-9VDC is supplied at no charge with many ComNet products
