*1. Nominal value at rated load. The specified derating is required to select an appropriate fuse capacity.
*2. Cutoff characteristics (25°C): 300% five seconds min. and inrush current of 20ms.
*3. A preventive circuit for inrush current is not built in the 24 VDC control power supply. Customer
must design the protective circuit.
*4. Make sure the current capacity is accurate. For an FSP Amplifier with cooling fan built-in, an inrush
current flows; 200% of the current capacity (in the table above) for two seconds, when turning ON
the control circuit.
5.2. Main Circuit Wiring
FSP Amplifiers are suitable under the following conditions.
With 100 V class: Less than 5000 A
rms
, 120 V maximum.
With 200 V class: Less than 5000 A
rms
, 240 V maximum.
With 400 V class: Less than 5000 A
rms
, 480 V maximum.
FSP Amplifiers must be used with UL-listed fuses or circuit breakers, in
accordance with the National Electrical Code (NEC).
