For single-phase divide by 2. Note: PT Primary Voltages shown are the line to neutral value for 3-phase / 4-wire circuits. Scale Watts Formula: The limits of full-scale values depend upon the rating of the instrument and the current and potential transformer ratios used. In order to determine whether the desired full-scale value is within limits, the following calibrating-watts formula and table are used. If the calibrating watts value falls within the range shown in the table for the instrument rating, the scale is acceptable. Calibrating Watts/Element = Desired full-scale value in watts or vars CW (PT Ratio) x (CT Ratio) x K Where K = 1 for 1-phase/2-wire circuits K = 2 for 1-phase/3-wire, 2-phase/3-wire, 2-phase/4-wire, 3 phase/3-wire circuits K = 4 for 3-phase/4-wire circuits Except K = 1.1547 for var models (10328 -- & 103812 -- 10329 -- & 103742 --) 12 STANDARD CALIBRATING WATT RANGES FOR 5A 120V RATING Model Watt or Var (except below) 2 el.

Note: Accuracy is affected on suppressed-zero instruments. 2. High-sensitivity voltmeters -- DC voltmeters can be offered up to 20,000 ohms/volt. Voltmeters of high sensitivity draw less current from the circuit and are used on applications where the circuit current is so low that instrument resistance will appreciably affect circuit operation. 3. Special legends and/or scales may be obtained by special order. Maximum number of letters (counting spaces as letters) on vertical instruments is 25; on horizontal instruments, 30.

D IMENSIONS AND PANEL D RILLING 29 SWITCHBOARD INSTRUMENTS POWER SERIES Plus D IGITAL S WITCHBOARD M ETER POWER SERIESPlus fills the need for a high accuracy digital switchboard meter and transducer that can be configured in the field by an end-user, or when installed in new electrical equipment by an OEM. It eliminates requirements for a large inventory of dedicated instruments, and provides flexibility when new panel designs or system upgrades require changes in instrument transformer rat- ings. Our rugged metal case fits standard panel cutouts for switchboard meters and makes it a perfect replacement for less versatile instruments. POWER SERIESPlus can also replace separate power transducers and meters in new equipment designs. An overall good solution for reduced wiring, panel space reduction, improved accuracy, and lower system cost.

Most models are UL recognized under File E60579 and exceed IEEE472/ANSI C37.90.1 Surge Withstand Capability test. The "SWC" test assures maximum protection from damaging line transients caused by switchgear operation or lightning strikes upstream on the system. Power transducers provide an analog DC Voltage or Current output proportional to an AC input. The input typically comes from the secondary of potential and/or current transformers such as Standard transducer inputs / outputs Input 0-5 Amp AC, 60 Hz C U R R E N T 0-1 mA output / self-powered/60 Hz 0-1 mA output / self-powered / rated 50/60 Hz True rms / 0-1mA output / 120V auxiliary power 4-20mA output / 120V auxiliary power True rms / 4-20mA output / 120V auxiliary power 3 in 1 transducer, 0-1mA output / self-powered V O L T A G E 0-1 mA output / self-powered/rated 60 Hz 0-1 mA output / self-powered / rated 50/60 Hz True rms / 0-1mA output / 120V auxiliary power 4-20mA output / 120V auxiliary power True rms / 4-20mA output / 120V auxiliary power 3 in 1 transducer, 0-1mA output / self-powered F R E Q U E N C Y Frequency 1.0 Hz deviation, 0-1mA output Frequency 1.0 Hz deviation, 4-20mA output Frequency 2.0 Hz deviation, 0-1mA output Frequency 2.0 Hz deviation, 4-20mA output Frequency 5.0 Hz deviation, 0-1mA output Frequency 5.0 Hz deviation, 4-20mA output Frequency 10 Hz deviation, 0-1mA output Frequency 10 Hz deviation, 4-20mA output Input 0-150 VAC, 60 Hz Input 120VAC, 60 Hz, self-powered Input 120V, 5A AC, 60 Hz, self-powered W A T T S * Watt 1P2W, 0-1mA output (1 Element) Watt 1P2W, 4-20mA output (1 Element) Watt 3P3W, 0-1mA output (2 Element) Watt 3P3W, 4-20mA output (2 Element) Watt 3P4W, 0-1mA output (212 Element) Watt 3P4W, 4-20mA output (212 Element) Watt 3P4W, 0-1mA output (3 Element) Watt 3P4W, 4-20mA output (3 Element) Input 120V, 5A AC, 60 Hz, self-powered V A R S * VAR 1P2W, 0-1mA output (1 Element) VAR 1P2W, 128mA output (1 Element) VAR 3P3W, 0-1mA output (2 Element) VAR 3P3W, 128mA output (2 Element) VAR 3P4W, 0-1mA output (212 Element) VAR 3P4W, 128mA output (212 Element) VAR 3P4W, 0-1mA output (3 Element) VAR 3P4W, 128mA output (3 Element) 150V and 5A AC. The output is linked to remote monitoring equipment such as meters, recorders, PLC's, SCADA or Energy Management systems. For most industrial monitoring needs, 0.5% accuracy is acceptable, and our 2469 Series exceeds this requirement. Most power utilities require a higher level of accuracy; and our 2489 series is a superior choice for those applications. Below, are the most popular models of both the 2469 and 2489 Power Transducers.

The last digit is the multiplier, it is equal to the number of zeros of the primary current. Some transformers will have 3 MSD (ex. 125:5). The multiplier will go after the third digit. An example of a 125:5 CT is 2RL-1250 36 SFT RL RBL RBT Notes: (1) Yokogawa Current and Potential Transformers are component recognized under UL E93779 and CSA LR89403 (2) All CT's are insulation class 0.6kV, BIL 10kV full wave.
