MOV's lang ang laman ng mga yan....
Tony, Hindi, MOV ang, laman eh. nakita ko yung demo at yung spec sheet. Pag, MOV, cllipped yung waveform. May 2 units ako dito , and yun lang mahirap isabak sa actual kasi wala naman akong testing eqpt. So asa lang sa data sheet ng manufacturer. Di naman mabuksan kasi covered ng epoxy. Sure lang na di MOV. pero maganda sana kung mabuksan ko ito or ma paxray
I checked the waveforms again, what happens is the transient voltage is absorbed by the device then slowly released to the output. so sa output wave, tumaas ng 6% yung voltage niya after the transient voltage came in. Unlike sa MOV, unti unting nasusunog yung MOV dahil sa pumapasok na surge. Though MOVs are the cheapes way to protect against surges talaga.
