This document introduces the different series and features of PULS's DIN rail mounted switched-mode power supplies. The Y-series is suitable for building redundant power supply systems or isolating sensitive loads. The X-series is suitable for applications with low requirements for output voltage fluctuations and power outage hold-up time. The Q-series is suitable for applications with high requirements for performance, technology, and flexibility. The C-series is a cost-effective product series that sacrifices some features while ensuring PULS quality. The U-series is for smoothing various power grid voltage fluctuations or power outages. The Z-series includes installation accessories. The document lists the specific models of each series.
The guide presents the six PULS DIN‑rail power‑supply series (Y, X, Q, C, U, Z), describing their key features, typical applications and the range of output voltages and power levels available. It includes detailed tables of product models, electrical specifications, dimensions, efficiency, and compliance information.
Technical data such as input voltage ranges, conversion efficiency, power factor, ripple, MTBF and operating temperature limits are provided for each model, helping engineers choose the right unit for redundancy, buffering, or standard power‑conversion needs. This manual is written in Chinese.
| Input voltage (AC) | 100‑240 V |
|---|---|
| Conversion efficiency (ML15.051) | 77.2 % |
| Power factor (ML15.051) | 0.44 |
| Dimensions (ML15.051) | 22.5 × 75 × 91 mm |
| Weight (ML15.051) | 130 g |
They accept an AC input voltage of 100‑240 V (with variations for specific models).
The units are rated for temperatures from –10 °C to +70 °C (some models up to +80 °C).
