and maximum output power.
(*2) For cases where conformance to various safety specs (UL, CSA, EN) are required, input voltage range will be 100 - 240VAC (50/60Hz).
(*3) First in-rush current. Not applicable to the first 0.2ms in-rush current flowing into the power supply noise filter.
(*4) Measure with JEITA RC-9131A probe, Bandwidth of scope :100MHz. (at 100uF electric capacitor and 0.47uF film capacitor on the test fixture board.)
(*5) 85 - 265VAC, constant load.
(*6) No load-Full load, constant input voltage.
(*7) Constant current limit with automatic recovery. Over current condition for more than 5 seconds will cause the
output to shutdown.
Output current exceeding maximum rated output current for more than 10 seconds continuously
will result to output shutdown.
(*8) OVP circuit will shut down output, manual reset (Power cycle) or ON/OFF CNT signal reset.
(*9) At 100/200VAC, nominal output voltage and maximum output current.
(*10) Measured by the each measuring method of UL, EN and CSA (at 60Hz).
When using it as a patient care equipment, all outer surfaces of the equipment shall be
constructed of nonconductive material. See clause 19.5DV.2 of UL60601-1.
(*11) Ratings - Derating at standard mounting.
- Load (%) is percent of maximum output power or maximum output current, whichever is greater.
- As for other mountings, refer to derating curve.
(*12) As for UL60601-1, EN60601-1 and CSA-C22.2 No.601.1-M90 (C-UL) basic insulation.
(*13) Peak output current is less than 10 seconds, and duty 35% max. (200VAC Line only)
