Q&A

Q : Can I order nonstandard input rectifier?
A : Yes, you can specify an input of rectifier according to your site’s voltage. We will design rectifier’s input voltage per your request.


Q : My location have variation of AC input voltage. Can I have +/- 30% input tolerance?
A : Yes, please give us both high and low voltage’s record in the past 6 months. We will design one fits with your voltage variation.


Q : We have vented battery type with equalizing voltage required. Recently, we are planing to replace VRLA battery which doesn’t need equalizing voltage in the future. Does that rectifier need to be modified or replaced also?
A : No, You just switch from an auto mode to manual mode, then adjust its voltage according to battery required.


Q : Can I parallel new rectifier with existing one?
A : Yes, please check an output voltage and voltage regulation, it must be in the same platform. If not, our engineer can design parallel module that fits any of them.


Q : Can I order +/-5% for silicon dropper?
A : Yes, please provide us your selected battery brand and model. We will calculate floating and equalizing voltage for silicon dropper design.


Q : We need to have battery installed in rectifier cabinet. Will that affect batteries’ and rectifiers’ lifetime?
A : The gas will be drained during battery charging process which causes harm to electronic circuit. Moreover, heat from transformer will also reduce your battery lifetime. We suggest you to divide battery and rectifier into parts. Also it both needs to be designed for cabinet.


Q : Can we have communication interface from rectifier to internet or network?
A : Yes, it’s an optional.


Q : Can we have the same dimension and specification with an existing rectifier due to space of installation?
A : Yes, we can design depending on your existing system.


Q : How long of an operation lifetime for industrial rectifier?
A : The design lifetime is 20 years depending on installation environment and usage.


Q : Can we have an engineer checked on rectifier before budget setup?
A : Yes, please call us to make an appointment.


Q : We do not have a critical load which is acceptable for power down. Do we need industrial grade rectifier?
A : No, due to a long-term saving investment you should install se-mi industrial grade rectifier to your system.


Q : How long does a warranty last?
A : The total limited warranty lasts for 5 years, 2 years for full warranty and extra 3 years for service fee exempted.


Q : How can I contact for futher inquiry?
A : Please email your inquiry to support@shinozawa.co.th or call +66 2108 8707
