SNP-Z20 Series

Product catalog summary

Overview: The SNP-Z20 Series is a general-purpose power supply with a power factor correction (PFC) feature, offering 200W output. It is designed for universal applications with a range of models tailored for specific outputs and requirements.

Specifications:

Input: Voltage range from 90 VAC to 264 VAC, frequency between 47 Hz and 63 Hz, and a power factor greater than 0.93.
Output: Efficiency ranges from 82% to 87% depending on the model. Hold-up time is greater than 20 ms at rated load and 115VAC.
Protection: Includes auto recovery for overload and short circuit protection, and latch-off for over-voltage protection.
Environmental: Operating temperature ranges from 0°C to 70°C with derating above 50°C. Storage temperature ranges from -20°C to +85°C.
Mechanical: Dimensions are 106.7 x 203.2 x 38.1 mm, with a net weight of approximately 740 g per unit.

Compliance and Safety:

EMI compliance with EN55022 "B" and harmonics with EN61000-3-2 class D.
EMS compliance with EN61000-4 series standards.
Safety certifications include UL 60950, UL 60601-1, CSA C22.2 No. 234 & 60601-1, and TUV EN60950-1 & 60601-1.

Model-Specific Output Specifications:

Each model provides specific voltage and current outputs with defined ripple, noise, and regulation parameters. For example, the SNP-Z201 model offers outputs of +5V, +12VA, and +12VB with specific load and voltage accuracy requirements.
Output performance includes turn-on and turn-off waveforms, line frequency ripple, and step response for voltage changes.

Performance Characteristics:

Performance metrics include switching frequency ripple, hold-up time, and over-voltage protection trip points.
Step response tests for +5V and +12V outputs demonstrate the system's response to load changes.

Additional Notes:

Each output can provide up to the maximum load separately at startup, but continuous operation beyond maximum output power is not allowed.
Efficiency and hold-up time are measured at rated load and nominal line conditions.
