1. Product Overview

      YDC-DDT series single-phase tower UPS is dedicated to low-power single-phase electricity usage scenarios, completely different from three-phase industrial UPS models such as EP-KL and YDC three-in single-out series. Adopts mature DSP full digital online double conversion technology, which can filter voltage fluctuation, surge, harmonic clutter from civil and commercial mains, and output stable pure sine wave power for IT equipment, testing instruments and monitoring hosts.

      The whole series unifies 4.3-inch touch color screen, consistent operation interface for all S/L versions, supporting Chinese & English switching, real-time electrical data display and automatic fault recording. The product is divided into two structural specifications: S built-in battery version for short emergency power failure, plug-and-play without additional battery configuration; L external battery version reserves battery wiring terminals, users can match multiple battery packs to realize long-time power backup.

      Optimized silent fan duct design keeps running noise below 42dB, suitable for quiet office and home environment. Complete multi-layer safety protection circuit and multiple communication interfaces support distributed multi-store centralized remote monitoring, and accept customized OEM services for overseas market.

2. Five Core Product Advantages

2.1 Unified 4.3" Touch LCD, Consistent Operation Experience

      All YDC-DDT001~010 S/L models are equipped with the same 4.3-inch color touch screen, unified menu logic, reducing after-sales training cost; local check voltage, load, battery, temperature without external display device, one-key fault self-check function built-in.

2.2 S/L Two Versions to Meet Different Backup Demands

   ● S suffix built-in battery model: Integrated standard lead-acid battery group, complete machine delivery, plug and play, ideal for office, home short power outage protection;

   ● L suffix external battery model: Cancel built-in battery space, reserve large-capacity wiring port, freely collocate 8~16pcs 12V batteries to extend standby time, fit laboratory and all-day monitoring equipment.

2.3 Ultra Wide Voltage Input & High Efficiency Operation

      120~275Vac wide input voltage range, stable operation in old residential areas and suburban unstable power grids; output power factor reaches 1, peak efficiency up to 95.5%, low standby power consumption to save long-term electricity cost.

2.4 Ultra-Low Noise Silent Design

      Intelligent variable speed fan, automatically adjust rotation speed according to load and temperature, 1-meter operating noise ≤42dB, no obvious buzzing interference in daily office and living space.

2.5 Complete Protection & Expandable Communication

      Integrated overvoltage, undervoltage, overload, short circuit, battery over-discharge, overheating six major protection mechanisms; standard RS232 + USB communication, optional SNMP monitoring card to build cloud centralized management platform for chain stores.

3. Typical Application Scenarios

     1.Small enterprise office computers, designer workstations, home server hosts

     2.Chain convenience stores, shopping mall counters, front desk cash register equipment

     3.School classroom multimedia, community monitoring weak current box

     4.Small medical testing instruments, laboratory precision measuring equipment

     5.Beauty salons, small studios, household intelligent equipment backup power

6. Global Customer FAQ

Q1: What is the difference between S and L suffix YDC-DDT models?

A1 S = built-in integrated battery short backup version, ready to use out of box; L = external battery long standby version, can connect multiple battery groups to extend power supply time.

Q2: Are all YDC-DDT models equipped with the same touch screen?

A1 Yes, all YDC-DDT001 to YDC-DDT010 S/L share unified 4.3-inch color touch screen with identical operation logic.

Q3: Can multiple chain store UPS be managed remotely uniformly?

A3 After installing optional SNMP card, all distributed units can be accessed by cloud monitoring platform for unified data view and fault alarm push.

Q4: Is the noise suitable for home and office environment?

A3 Max operating noise only 42dB, low-speed operation under light load without disturbing daily work and rest.

Q5: Support overseas voltage and language customization?

A3 We provide OEM modification for screen language, input/output voltage and charging parameters to match different regional power standards.
