PAM-01 Technical Specifications
|
 | ±1º of actual power angle |
| 0.1º of indicated power angle on the instrument’s digital internal and optional remote digital display meters. |
| Maximum time is 60 seconds upon restoration of the lost input quantity. Typical recalibration is 30 seconds. |
| ROTOR is an input signal from either a stationary magnetic speed pickup adjacent to a turbine generator shaft mounted toothed wheel or an infrared optical pickup. ROTOR input signal frequency is in the range of 240 to 6000 Hz. Usable input amplitude range is 5 volts peak to peak (p-p) to 100 volts p-p. A powered input jack is provided for supporting the EUMAC, Inc. model OP-1 Optoprobe. Input impedance is 100K Ohms. |
| REF is an input signal from synchronous machine three phase potentials. Nominal input of 95 to 130 vac, 60 Hz. |
| REV
is a once per revolution input signal from either a magnetic pickup or
infrared optical pickup. Usable input amplitude range is 5 volts peak to
peak (p-p) to 100 volts p-p. A
powered input jack is provided for supporting the EUMAC, Inc. model OP-1
Optoprobe. Input impedance
is 100K Ohms. A REV input is
required for self-calibrating operation. |
| ANALOG OUT is a ± 12vdc output signal proportional to power angle, δ. Calibration factor of 10º/volt into a 10K Ohm load or greater. |
| 4 to 20 ma OUT is a 4 to 20 milliampere current loop output with a scale factor of 12.5º/ma into a load of 1000 ohms or less. |
| REMOTE
METER – Is a powered output designed to connect to a EUMAC, Inc. model
PAM-RM remote 3½ digit panel
meter. |
