SNAP-AIPM Modules

Description

SNAP power-monitoring analog input modules provide an

efficient way to monitor AC voltage and current using a SNAP

PAC rack-mounted controller or SNAP PAC brain. These

modules can be used with both standard wired SNAP PAC

brains and controllers and Wired+Wireless

Three power-monitoring modules are available:

• The SNAP-AIPM monitors single-phase AC power.

• The SNAP-AIPM-3 monitors three-phase AC power using

• The SNAP-AIPM-3V monitors three-phase AC power using

All modules mount on a SNAP PAC rack right alongside digital,

analog, and serial SNAP I/O

SNAP power-monitoring modules help you measure and

control power usage, so you can reduce costs, maintain power

quality, and track energy use. If they are part of a SNAP PAC

System running a PAC Control

automatically perform additional calculations and respond to

any problems the module reports.

SNAP racks use a retention rail locking system that holds

modules securely to the rack. Normally, a hold-down screw is

not required. However, for applications that require additional

module security, each module has provisions for two 4-40 by

½-inch standard machine screws to hold each module in

position on the SNAP rack.

SNAP-AIPM

The SNAP-AIPM individually and simultaneously measures

single-phase AC volts RMS and amps RMS and calculates true

power and volt-amps. Power factor can then be calculated

from true power and volt-amp values. Because true power is a

signed value, either leading or lagging power factor can be

calculated.

The SNAP-AIPM module is designed for 85–250 volts and 0–

10 amps, but it can also monitor AC line currents greater than

10 amps using a standard 5-Amp current transformer (CT) of

suitable ratio. For line voltage larger than 250 VAC, use a step-

down potential transformer. If hazardous voltage or current is

to be monitored, an interposing potential transformer and a

CT must be used for safety.

The SNAP-AIPM module offers four channels (points) of data,

two from wired inputs and two calculated by the module:

To calculate power factor, simply use the data in points 2 and 3

in the formula: Power Factor = (True Power Magnitude)/ (volt-

amps).
