The APMC-406A is a monitor for 3-phase power lines that supports variable frequency power monitoring. It measures parameters associated with 3-phase power lines as follows:
- 13 steady state and 3 transient parameters for measurement of aircraft electrical power characteristics
- active, apparent power and their ratio
The APMC-406A has a programmable gain amplifier, an analog-to-digital converter and a 65,536-point conversion table for each of the six channels. All six channels are sampled simultaneously at 2 Msps.
