1. Product Overview

      Different from large-capacity 3P3P tower UPS, YDC series adopts three-phase input and single-phase output architecture, specially developed for scenarios with three-phase mains access but only single-phase terminal loads. It applies mature online double conversion + DSP full digital control algorithm, can actively filter grid voltage fluctuation, surge, harmonic and spike interference, output stable pure sine wave power for precision loads.

      The whole series adopts ultra-compact vertical tower structure with unified cabinet size, small floor space and neat appearance, suitable for placing inside ordinary server cabinets and narrow equipment corners. The built-in LCD screen can realize local parameter check, fault prompt and operation setting without external display device. Rich communication interfaces are reserved, SNMP card can be optionally installed to realize remote centralized monitoring of multiple distributed branch sites.

      With graded weight design for different capacities, the unit is easy for manual handling and on-site installation. Intelligent battery management function supports adjustable charging parameters, effectively prolongs battery service life and reduces daily operation and maintenance difficulty for scattered small power sites.

2. Three Core Product Advantages

2.1 Mature Digital Power Solution, Stable Power Quality

   ● Adopts industry-proven DSP full digital control for online double conversion topology, quickly suppresses various grid disturbances such as voltage deviation, surge and peak pulse.

   ● Input wide voltage range 190~520Vac, strong adaptability to unstable commercial mains in suburban areas and business parks.

   ● Output voltage regulation accuracy ±1%, THDi ≤3% for linear load, ≤5% for non-linear load, delivers clean power for servers, testing instruments and network equipment.

2.2 Compact Integrated Structure, Easy for Distributed Deployment

   ● Unified slim cabinet size 190×610×330mm, occupies very little floor area, beautiful appearance and space-saving.

   ● Light body weight: 19.9kg(10kVA)/20.2kg(15kVA)/21.3kg(20kVA), no special handling tool required for installation.

   ● Built-in LCD human-machine interface, independent operation without extra monitoring terminals, perfect for unattended branch offices.

2.3 Comprehensive Protection & Intelligent Operation Management

   ● Complete multi-level protection: input over/under voltage, output overload, short circuit, inverter fault, battery over-discharge protection; pre-start self-diagnosis function.

   ● Intelligent battery management: adjustable charging voltage, current and floating charge mode, automatic balance between battery strings.

   ● Standard RS232, USB, EPO dry contact interfaces, optional SNMP/NetCard expansion, support remote cloud monitoring and centralized management of multi-site UPS units.

6. FAQ

Q1: What is the advantage of 3P1P structure compared with single-phase input UPS?

A1: It uses three-phase mains power supply to balance grid load, suitable for buildings with three-phase incoming line while most loads are single-phase office equipment, avoiding three-phase unbalance problem.

Q2: Are three models the same in cabinet size?

A2: Yes, 10/15/20kVA share unified 190×610×330mm cabinet, only net weight differs slightly, convenient for unified installation and cabinet layout planning.

Q3: Can it realize remote monitoring for multiple branch offices?

A3: Optional SNMP network card, connect to centralized monitoring platform to manage distributed UPS devices of all branches uniformly.

Q4: How about the overload performance under battery mode during power failure?

A4: Battery mode has strict graded overload protection, fast bypass switching for severe overload to protect host and load safety.

Q5: Suitable for bulk procurement of chain commercial projects?

A5: Compact unified appearance, simple installation and consistent parameters, very suitable for centralized bidding procurement of chain stores and institutional branches.
