New love dwyer 100 a scr, phase-angle, 1PHASE
LAST CHANCE OFFERING AT THIS RIDICULOUSLY LOW PRICE! HAVE 13 PIECES LEFT FOR INDUSTRIAL PROCESS APPLICATIONS. SOLID 100% SELLER REPUTATION. LESS THAN SIX DAYS LEFT!
New Phase-Angle-Fired SCR's, Love manufactured for Dwyer, 100 Amp Single-Phase SCR, Model #1028A, 208 Volt AC control: For Excellent Control of Resistive or Transformer-Coupled Loads.
Phase angle firing is best suited to Resistive/Inductive loads and special types of loads such as Infrared or quartz heaters, transformer coupled, or tungsten loads. The wave form for each half cycle is automatically adjusted to allow only the desired power to the load.
Control Signal Inputs are: 4-20 mA, 0-5/15 Vdc, or Manual Setpot. Electrically isolated Command Signal from Heat Sink & Line & Load. Soft-Start feature, Full Factory set of schematics,& manual included.
