Online Transformerless UPS series
Online transformerless UPS series(200kVA-1200kVA) is a power supply device that uses high-frequency switching technology and does not require a traditional power frequency transformer. It uses double conversion online technology to always provide stable and pure power to the load, and when power is off, it uses batteries to ensure continuous operation of the equipment.
High reliability
Wide input voltage range, line voltage range is 138-485V, UPS will derate to 40% when input voltage is below 305V.
Thickened conformal coating, applicable for harsh environment such as high heat, high humidity, dust.
Intelligent management
With 7 inches (Standard) and 10 inches (Optional) colorful touch LCD screen.
Support recording and exporing history logs and fault logs.
Support SNMP, RS232, RS485, BMS, Dry contact interface.
Strong load capacity
Output power factor is 1.0, UPS can supply power to 100% unbalanced load.
High adaptability for load, it can connect full inductive load or capacitive load.
High input power factor, it is up to 0.99.
3-level topology design, efficiency is up to 96%.
THDi＜3% (100% linear load).
The UPS will work in sleeping mode when the load is very small.
Compatible with VRLA or lithium battery.
Data center: Ensure stable operation of servers and network equipment.
Medical equipment: Ensure continuous power supply for precision medical instruments.
Industrial automation: Support automated production lines and control systems.
Communication system: Maintain power supply for communication base stations and network equipment.
1
Does this UPS require external batteries? What types are supported?
Yes, the HP33ETS series is transformerless and requires an external battery bank. It supports both Valve-Regulated Lead-Acid (VRLA) and Lithium-Ion (Li-ion) batteries, allowing flexible runtime configurations (30 minutes to multiple hours).
2
What is the system efficiency? Does ECO mode compromise load protection?
* Double Conversion Mode: Up to 96-97% efficiency.
* ECO Mode: Achieves 98% efficiency with intelligent bypass technology.
* Output remains filtered and stabilized in ECO mode, ensuring uninterrupted protection for critical loads.
3
Does it support redundancy? How is redundancy achieved?
Yes, the HP33ETS supports N+1 redundancy and parallel scalability. Built-in controllers synchronize multiple UPS units, enabling automatic failover to redundant units with zero transfer time during outages.
4
Is it compatible with harmonic-sensitive loads (e.g., servers, variable frequency drives)?
Absolutely. The output voltage has <3% Total Harmonic Distortion (THD), safely supporting non-linear loads like IT equipment and industrial motors. Optional input harmonic filters are available for enhanced compatibility.
5
How is battery lifespan maintained? Can batteries be hot-swapped?
* An integrated Battery Management System (BMS) optimizes lifespan via temperature compensation, automated self-tests, and charge/discharge cycling.
* Batteries are hot-swappable, allowing replacement without downtime.
6
How does the system switch to backup power during a fault? What’s the transfer time?
* Dual safeguards: Static Bypass (instantaneous transfer) and Manual Maintenance Bypass. Transfer time is 0 milliseconds.
* If overloaded or faulty, the UPS automatically switches to utility bypass to ensure continuous power.
7
Is remote monitoring supported? What protocols are integrated?
Yes. Protocols include SNMP, Modbus TCP, RS485, and dry contact alarms. Monitor real-time data (load, battery health, temperature) via a web interface or integrate with third-party DCIM/BMS platforms.
8
What are the environmental requirements for installation? Is a dedicated server room needed?
* Operating Conditions: Temperature 0-40°C, humidity 0-95% non-condensing.
* Designed for ventilated spaces; no dedicated server room required. Ensure adequate clearance for airflow (see installation manual).
9
What is the recommended maintenance schedule? Does it require specialized technicians?
* Preventive Maintenance: Inspect every 6 months (clean filters, update firmware, etc.).
* Modular Components (fans, capacitors) allow field-replaceable parts. No vendor expertise is needed for routine replacements.
10
What is the warranty coverage? Is global support available?
Standard Warranty: 1 years (extendable to 3 years), covering equipment and OEM batteries.
Global Service: Huawen New Power provides 24/7 technical support with 2-4 hour response times (varies by region).
