This includes real power (W), real power factor (PF) reactive power (VAr) delivered to a load. Bi-directional capability means power can be measured in both directions, with indication of import and export. Especially in applications like Locomotive, Electric vehicle where motoring and regeneration occurs with power and energy. Models are available in a variety of configurations with current ranges up to 1000A and nominal voltage ratings up to 600V. Models are available in 1, 2 and 3 element versions; suitable for all single-phase and three-phase power systems. RS485, CAN BUS, Modbus and Analog output signals are available. Forward (consumed) power is indicated with a positive polarity and reverse (generated) power with a negative polarity. Unidirectional outputs (4-20mA) indicate forward (consumed) power, 4-12-20mA allow for both directions. Easy scaling of VTs and CTs is possible. All outputs are galvanically isolated from the measured inputs and instrument power.<\/p>\n<p>The sensor power input is designed to operate over a wide range associated with process control and sub-station auxiliary dc supply systems.\u00a0 Some typical applications are voltage monitoring in Solar PV, Dc drives, UPS, Frequency Changers, Process Control, Rail Transportation, and EV. For all products, a NIST\/NPL\/UKAS traceable calibration certificates of conformance are available.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>WT1ph Watt Transducer order codes<\/strong><\/p>\n<p>WT1ph \/ Voltage range \/ Current range \/ Scaling \/ output type \/ instrument power<\/p>\n<p>WT3ph \/ Voltage range \/ Current range \/ Scaling \/ output type \/ instrument power<\/p>\n<p>WX-3ph \/ Voltage range \/ Current range \/ Scaling \/ output type \/ instrument power<\/p>\n<p><strong><br \/>\nOrder code examples:<\/strong><\/p>\n<p>WT1ph \/ 120V \/ 500A-CT \/ 500:5 \/ Std \/ 4-20 \/ 24Vdc<br \/>\n120Vac input, 500\/5A input, CT type 500:5, 4-20mA output with 24Vdc aux power input<\/p>\n","protected":false},"excerpt":{"rendered":"<p><em><strong>AC-DC Watt Transducer,<\/strong><\/em><br \/>\n<em><strong>Models WT1ph and WT3ph,<\/strong><\/em><br \/>\n<em><strong>measure all waveform types from sinewaves,<\/strong><\/em><br \/>\n<em><strong>on\/off dutycycle to complex VFD applications,<\/strong><\/em><br \/>\n<em><strong>DC-20kHz<\/strong><\/em><\/p>\n","protected":false},"featured_media":5968,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-global-header-display":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":""},"product_cat":[22],"product_tag":[],"class_list":{"0":"post-5969","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-22","7":"desktop-align-center","8":"tablet-align-center","9":"mobile-align-center","11":"first","12":"instock","13":"shipping-taxable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/product\/5969","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/types\/product"}],"version-history":[{"count":2,"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/product\/5969\/revisions"}],"predecessor-version":[{"id":5971,"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/product\/5969\/revisions\/5971"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=\/wp\/v2\/media\/5968"}],"wp:attachment":[{"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5969"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=5969"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.chinatech-cn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=5969"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
