Description
The SBU81 series is a family of open frame ITE power supplies that are designed to offer 80W continuous output power with a dual to triple output of 5v-15v (coming with a universal input of 90-260 Vac) at efficiencies up to 78%. The power modules can operate in an operating temperature range of 0 to +70°C, and an active power factor correction (PFC) is included to improve the power quality.
The ITE power supplies are burn-in test conducted and offer class I operation, overload protection (OLP), and crowbar mode overvoltage protection (OVP) to ensure the safety of the user and device in which the power supply is installed. The series owns comprehensive protection designs along with all-inclusive safety certifications and conforms to major international safety standards including UL/IEC/EN/CAN/CSA C22.2 62368-1. All modules are fully compliant with RoHS directive.
The SBU81 switching power supplies are designed for ITE applications and are ideal for communication equipment, industrial PC (IPC), electrical measuring instruments, etc.
