Pro motor features a constant torque 48 frame ECM that serves as a smart alternative to the original X13. This motor’s high moisture design is a direct drop-in replacement for the X13 motor with enhanced moisture robustness beyond that of X13. All applications featuring the X13 motor will now use the Endura Pro motor. Variable speed, constant torque, brushless DC motor. 115V, 208-230V, and 277V AC single-phase input, 50/60Hz. Designed for direct-drive blower applications. Available in 1/3, 1/2, 3/4 and 1 HP ratings. Operating speed range of 600 – 1100 rpm. And cUL recognized component. Up to five constant torque settings controlled by 24VAC inputs. Same connector block as original X13. Motor and controls designed for improved reliability compared to X13 in high moisture environments. ECM Toolbox-based programming software. Designed for extended life beyond that of X13 in harsh, moist environments. Efficiency up to 80%. Drop-in replacement for X13. Application simplicity – Import X13 into Endura PRO programs in ECM Toolbox. Constant torque providing less static pressure limitations than PSC. Up to 33% greater efficiency than PSC in constant fan mode. Ideal to meet needs of 13 & 14 SEER. Attention Sellers – Get Templates Image Hosting, Scheduling at Auctiva. Com. Track Page Views With.
