Lenco has in stock Constant Voltage/Ferroresonant Transformers (Sine Wave Output) for immediate delivery. These transformers are designed to provide a relatively constant output voltage (±3%), with less than 3% distortion under full load and under 5% no-load GUARANTEED, while specified input voltages may vary by as much as +15 to -25%. Providing high isolation and fast response time (typically 1-2 cycles) these transformers are excellent at controlling voltage sags, surges, brownouts, noise and distortion.
All Lenco Constant Voltage/Regulating transformers are built to a UL recognized insulation system. They feature Compact Terminal Strips that provide the ultimate in safety due to all the metal parts either being fully enclosed or deeply recessed. These transformers are available from 50VA to 1500VA and in 120,240 and 480 volt 60 Hz. configurations. Special voltages and/or frequencies are available upon request.
Note: All in stock Lenco Constant Voltage Transformers include appropriate Capacitor.
