Hi ,I want to use arduino and SSR to control pump like this link
iwakiamerica,it is 24V DC(RD05H), and Starting Current almost 4A,working current is 1.6A
anybody can give me some SSR that can do this ,like crydom DC60S5 can do this with arduino PWM output?
thanks!!
anybody can help me,thank you
I'm not sure SSRs are recommended for PWM*.
From the datasheet, the turn-on/turn-off times are 20ms, indicating a PWM rate of just 1/((20+20) x 10-3) = 25Hz.
(Please don't bump after just two hours)
*yes, I know, your house thermostat and boiler operate low frequency PWM ;D
Most SSRs are 'zero crossing' which means they will only switch state at the frequency of the mains supply (when the AC voltage passes the zero mid point). It renders them useless for PWM which switches on and off at several kHz.
It's a DC pump anyway :

Close........ ;D
the datasheet should be this link

it seem has 0.1mms Turn-On Time...
