Level of Insulation:
Dielectric Strength testing is carried out as follows:
Primary mains circuit to earth - 2.25 - 2.35KVDC.
*Primary mains circuits to secondary: 4.25-4.35kVDC.
Outputs to earth are isolated to 200VDC.
*Important Note: This test is not possible with Y capacitors fitted to the unit as damage to these capacitors may occur.
It is also necessary to short circuit the outputs together and to earth.
Safety Approvals:
UL60950-1 and CSA22.2 No.60950-1 - UL Recognised. C-UL for Canada.
UL/CSA 60601-1 - UL + C -UL approval
IEC / EN60950-1 - CE mark.
CE marking when applied to any NV300 product indicates compliance with the Low Voltage Directive
in that it complies with EN60950-1 and with the ROHS Directive.
Fusing: Internal fuse (FS1): F6.3AH, 250V, 5x20mm
Symbols:
AC DC
Danger, shock hazard
Note: All output voltages/variants may not be available as standard units, refer to datasheet for standard
product range. These (and other variants) may be available as non-standard or custom units, please contact
