Description
Telecom rectifier systems advanced modular design makes the whole systemsmall, but it can provide enough power to meet the requirements of
Communica-tion and Power Industrial systems, consistent with the characteristics of therack-mounted.This System consisted by one rectifier
module or multiple rectifier modules andmonitor modules. The power of rectifier systems can be different by differentquantity rectifier
modules.The rectifier system provides load power, battery floatcurrent, and battery equalized current during normal operating conditions

B2B FAQ
Do you support BMS communication on your chargers?
Yes. Where the model supports it, the charger can communicate with the battery BMS over CAN or RS485 so charging stops at the values your BMS expects. The interface fitted to this model is listed in Key Specifications.
Can the charging curve be adjusted to our battery?
Yes. Charging voltage, current and the CC/CV stages can be set to your pack specification as part of an OEM / ODM order. Send your battery datasheet and we confirm the profile.
Can you supply the connector we already use?
Yes. We can fit your existing connector type and pin-out, or supply a matched connector and cable assembly.
Do you offer Custom Branding?
Yes. Custom Branding is available on the product label, housing and packaging for OEM and ODM programs.
How does sample development work?
Send your specification and target quantity. We confirm the configuration, provide a sample lead time and quote, then move to production once the sample is approved.
