(Note 1) The rated output is guaranteed at the rated input voltage (200/220/230VAC) to the power supply unit.
If the input voltage fluctuates and drops below 200VAC, the rated output may not be attained.
(Note 2) The 50%ED rating applies for a 10-minute cycle time consisting of ON for five minutes and OFF for five minutes.
(Note 3) The 3.7kW and smaller capacities are available with the MDS-B-SPA Series. Refer to Appendix 5 for details.
