Snap-On Load Detectors/Current Sensors LD-50 Load Detector and High Sensitivity Current Transformers • The revolutionary LD-50 snap-on load detector mounts on pre-wired systems without disrupting existing connections • Range of new applications such as monitoring relays and lamps, Hi/Low current limits, instrumentation, solid state switchgear, motor control, and much more • Broad frequency response: 30Hz to 15 kHz • Operating temperature: -55°C to 120°C • Measures currents up to 40 Amps RMS continuous, 120 Amps intermittent High Sensitivity Current Transformers • Excellent for low budget energy management and automation control API’s high sensitivity series of current transformers has been specifically designed for those applications where a low value of current is to be monitored. A primary winding is supplied (pins 1 & 2) which helps increase the sensitivity of the transformer. • Available pre-assembled or unassembled, to snap over existing wiring Electrical Characteristics • High reliability long lasting magnetic device • Output linear to within 3% from 2A to 20A of Input Dimensions and Construction Dimensions in inches VL Volts RL Ohms 2.0* 100 Is Sec DCR Sec Ind Accy at Accy at Amps Ohms H 100% Ip 10% Ip 0.02* 36 1.1 1.0% 0.3% P/N Load Current Ip(A) Turns Ratio Pri Ind mH Pri DCR Ohm 5361 5362 5363 5364 5365 5366 5367 LD-50 0.05 0.1 0.2 0.5 1 2 5 20 1000:400 1000:200 1000:100 1000:40 1000:20 1000:10 1000:4 1000:1 176 44 11 1.76 0.44 0.11 0.018 ** 15 3.7 0.93 0.15 0.038 0.01 0.0025 ** * Many customized output voltages and currents are available on special request, at same low price ** For LD-50, the one-turn primary is customer supplied The terminating resistor is customer supplied +1 814.272.2700 eis.apitech.com AHA 2/13 +1 855.294.3800 www.apitech.com
