Works as advertised
Appears to work fine, the relay was activated with a voltage between 2.5-5v DC, though it's obviously rated much higher. Only used it to switch 220v at 3A AC, can't comment on higher currents but it seems well built and works as advertised

POOR QUALITY!!!... LOOK FOR ALTERNATIVE.
I would seriously think twice about buying this cheap SSR, I had this installed in my 3d printer thinking it was working fine drove me mad trying to diagnose problem figured out eventually SSR was faulty and not doing its job although indicator light lit up making me think it was working fine, I'm pretty sure people who are rating this as a 4/5 star don't even know this is not working as the job for this SSR is to protect your rig from shorting, I think what this SSR does is allow current to run through but somewhere its not protecting the way it should and sends off all sorts of errors in some cases I can't put my finger on it as I'm not an engineer in this field, I basically ending up buying a premium SSR which worked straight away and got rid of all my headaches, I would look for a better alternative or if you can spend a bit more get a reliable/quality product.

Not good
Bought this a couple of weeks ago and installed it yesterday. Only worked for 10 minutes after which it failed to switch off completely and then pulsed on and off, only switching 500ma at 240 volts.

BUENA CALIDAD
BUENA RELACIÓN CALIDAD-PRECIO.

Nie odcina przepływu prądu całkowicie
W stanie wyłączonym przepuszcza aż około 100v z 230v więc ciężko to nazwać rozłączeniem obwodu. Żarówka świeci nadal tylko mniejszym światłem, świetlówka LED miga. Bez sensu.

ON-OFFを頻繁に 繰り返す設備の 接点式リレーの入れ替えには最適。
自作の 防獣対策 高圧発生機の 出力リレーを このソリッドステートリレーに置き換えたら 故障がなくなりました 。 ICの出力で ON-OFFできるので IC1個 リレー トランスで 完成 １秒サイクルの出力などは最適です。
