Current Transducer & Signal Amplifier Inquiry (采购产品): Current Transducer & Signal Amplifier Dear Sirs, I am looking for a substitution for the Spatron Current Transducer CLE-202001 and Signal Amplifier CLE-207100. Specifications are attached. Please advise if you have a compatible offering. · CURRENT TRANSDUCERS GENERAL FEATURES: *Accuracy ± 0.25% of Rated Output *Accuracy maintained from 0 - 6.5A input *Accuracy load-independent *Meets IEEE SWC test *Withstands 1.2 x 50*s 6kV crest impulse *Negligible temperature effect on accuracy *Excellent long term stability *Complete technical manual available GENERAL APPLICATIONS: *Transmission of current signals over long distance with no loss in accuracy *Energy Management Systems *Motor and Power Control Circuits GENERAL DESCRIPTION: The CLE-202001 transducer accurately converts a sinusoidal AC current to a proportional dc output current. The CLE-202031 transducer accurately converts three sinusoidal AC currents to three proportional dc output currents. The output current can be indicated on analog or digital instruments or feed data loggers, recorders, or computer inputs. The output can also drive analog to digital converters used in Energy Management Systems or other control systems, such as the Model CLE-207100 process amplifier. An extremely stable constant current amplifier permits the dc signal to be transmitted over long distance with no loss in accuracy. Excellent temperature and long term stability characteristics are provided. Premium selected solid state devices are used for increased reliability. The output is insensitive to load variations, making it ideal for remote instrumentation or control applications where long lead wires and varying load resistance is encountered. Full scale calibration of ±10% is provided through a sliding access port. A multi-turn adjustment potentiometer is provided for precise settings. Zero adjustments are not required. The transducer is self-powered for the entire input range and has a burden <.15VA. The 0.25% of rated output accuracy is maintained over the entire Input Range, permitting overloads to be measured with the same accuracy as the Rated Input. As long as the Compliance Voltage Limit (11 volts dc) is not exceeded, (loutxRL The transducers are designed to withstand the surge requirements of IEEE STD.472 and ANSI C37.90A (SWC). Additionally, the unit withstands an Impulse test of 1.2 x 50us, 6kV crest unidirectional and up to 100VRMS, 2 sec. across the output terminals. High dielectric withstand capability and complete input/output/case isolation is provided. The mounting dimensions and wiring connections match those of other commonly used transducers for ease in replacement. An in-line test jack can be provided as an option on the CLE-202001 to permit monitoring the output current while in service. Add the letter "T" to the catalog number to specify this option. Available on single phase version only. CLE-202001 SPECIFICATIONS: Input Range 0-6.5A Rated Input 5A Burden at 5A 60Hz <0.15VA Overload 10A continuous; 250A for 1 sec.

Output Open or Short Circuit Protected Open Circuit Output at Rated Input < 20Vdc · PROCESS SIGNAL AMPLIFIER APPLICATION: The Process Signal Amplifier Catalog No. CLE-207100 converts either a 0-1mAdc or 0-10Vdc transducer output to the input signal requirements of many recorders, process controllers and signal conditioners. The three most commonly used output signals are available, 1-5mA dc, 4-20mA dc or 10-50mA dc. These outputs are selectable by means of jumper strap provided with the unit. The Process Signal Amplifier is supplied connected for 4-20mA output with either a 0-1mAdc or 0-10Vdc input. 0.25% RO accuracy furnishes the tight accuracies required in transducer applications. Catalog No. CLE-207200 is used with transducers having a ± 1.0mAdc or ± 10Vdc Rated Output to provide a bidirectional output of 3±2mA dc, 12±8mA dc or 30±20mA dc. It is generally used with var and power factor transducers when lag & lead PF conditions are present. DESCRIPTION: The Process Signal Amplifier is an all-electronic device designed to provide a standard, non-isolated Process Signal output. Catalog No. CLE-207100 converts a 0-1mAdc or 0-10Vdc input into a field selectable output current of 1-5mA dc into a 0-4k(ohm0 load, a 4-20mA dc into a 0-1k(ohm) load or 10-50mA dc into a 0-400(ohm) load. Catalog No. CLE-207200 converts a 0+/-1mA dc or 0+/-10Vdc input into a bipolar field selectable output current of 1-3-5mA into a 0-4k(ohm) load, 4-12-20mA dc into a 0-1k(ohm) load or 10-30-50mA dc into a 0-400(ohm) load. The amplifier is protected against damage from transients, surges or overloads. The Process Signal Amplifier is housed in a sturdy steel can with injection molded plastic cover. This permits such features as unbreakable terminal block covers, sliding access ports for calibration and zero adjustments, and in-line test jack for monitoring output current during operation.
