SPECIFICATIONS
Table 2 contains specifications and operating limits of individual HSF-A 1500W Series models.
Table 3 contains specifications and operating limits common to all HSF-A 1500W Series Models.
These specifications are at nominal input voltages at 25°C and apply to all models unless other-
wise specified.
