LED Lighting Surge Protection Module > LSP10

Notes:

1. 5A max. continuous current for series connection.

2. Nominal Discharge Current (In)(A): The nominal discharge current is a measure of the SPDs endurance capability; 15 impulses of discharge current uses the 8/20us current waveform.

3. Maximum Discharge Current (Imax)(A): The maximum discharge current is a measure of the SPDs maximum capability; single impulse of discharge current uses the 8/20us current waveform. All

Devices pass maximum discharge current with possible, safe opening of thermal disconnect.

4. MLV – UL1449 Measured limiting voltage; the highest value of residual voltage measurements during the application of impulses of 8/20us nominal discharge current (In); an average voltage value of

15 impulses.

5. Up – IEC 61643-11 Voltage protection level; the highest value of residual voltage measurements during the application of impulses of 8/20us nominal discharge current (In); a rounding voltage value of

maximum measurement.

6. MCOV/UC: Maximum Continuous Operating Voltage - maximum r.m.s. voltage that could be continuously applied to the SPD.

7. The series modules can be used in parallel connections for the indication circuit connection.

8. * = - P or PM

9. Repetitive Surge Withstanding: 15 strikes at 10,000A (8/20us) with steady MLV/Up.
