Application Q&A
12. What surge level can GTEK LED power supply withstand?
Among GTEK LED power supplies, CLG and HLG have the highest surge capability. It can withstand heavy industry level of 4kV. If higher level is required, external ZNR (470V) or gas tube (500V) can be added as shown in figure 8. But, overall safety compliance must be taken into consideration. For application with numerous lamp sets, a SPD (Surge Protection Device) can be installed to meet surge regulation requirements.
