Certificate of Non-use of RoHS (10 Substances)
The UOHC 150W Series (UOHC3150) is an embedded AC-DC switching power supply (open frame/panel mount) designed for industrial devices. In addition to a design focused on stability, it is structured as a series with organized PFC, various protections, and EMC/EMI requirements.
Specifications include information that facilitates power supply selection and evaluation based on equipment operation conditions, such as peak output (conditional), full-range input (85–264Vac), and operation altitude up to 5,000m.
| Why choose UNIFIVE: As a power supply manufacturer with over 35 years of experience in power development, we offer comprehensive support from specification review to certification, mass production startup, and post-production support, all with a view to mass production adoption. Based on standard products, we offer flexible supply that accommodates small-lot prototyping and evaluation, small to mid-scale production, and large-volume production. We also support semi-customization, assisting with power supply selection from the specification planning stage for mass production adoption. |
Key Features
1) 150W-class Industrial Open-Frame Power Supply (with/without chassis or remote control options)
The UOHC3150 is available in a typical PCB-only configuration and with a chassis. It also supports options such as remote control and additional internal standby power (5V), providing flexibility to meet equipment-side operation requirements. Ideal for replacing existing models.
2) Technical Standards and Protection Circuits
The series is designed to comply with 60065-1 / 60335-1 / 60601-1 / 60950-1 / 61558-1 / 62368-1. Applicable conditions vary by model and should be confirmed individually.
Protection circuits include short circuit protection / overvoltage protection / overcurrent protection / overtemperature protection, and also Brown In / Brown Out protection.
3) High Efficiency (up to 89%) and Defined PFC Specifications
The efficiency is listed as up to 89%, with detailed efficiency and power factor (typical) based on input conditions provided in the specification sheet. Useful for organizing input requirements including PFC.
4) Peak Output (Conditional) for Equipment with Load Variations
With conditional peak output (up to 300W), this series supports peak load requirements (duration and duty cycle). Helpful for organizing requirements for startup and temporary load variations.
5) EMC (Emission)
Emission standards include FCC Part15 Class B / FCC Part18 Class B, CISPR 11 / 14 / 32 (EN55011 / EN55014-1 / EN55032), VCCI Class B, and BS EN standards.
6) Immunity
Immunity standards include EN 55035 / BS EN 55035, EN60601-1-2 / BS EN60601-1-2, and EN55014-2 / BS EN55014-2.
Effective Use Cases
- When using a 150W-class open-frame power supply as an internal power supply for industrial equipment
- To define power requirements that include conditional peak output (up to 300W) for startup or variable loads
- To proceed with equipment design with clear input-side conditions such as PFC (power factor) and inrush current
- To organize protection requirements including Brown In/Brown Out and reduce operational risks due to input fluctuations
- To select power supply configurations based on device control requirements such as internal standby power (5V) and remote control
- To select an internal power supply considering environmental installation conditions such as operation altitude up to 5,000m
Applications
Widely applicable as an internal power supply for industrial equipment.
- Industrial equipment/control devices
- Information and communication equipment/peripheral devices
- Various devices requiring internal power supplies, etc.
