3 Phase Online Low Frequency Ups / 10KVA - 120KVA 50HZ Energy UPS

Introduction: Powervalue (Ⅱ) is upgraded DSP controlled Online LF UPS with output isolation transformer. It can be your perfect large capacity power shield for your critical and industrial load.

QUALITY POWER SUPPLY

HRD PV(II)series is an On-Line double conversion (VFI) UPS with isolation output transformer, unit capacity from 10KVA to 400KVA. It is immune to the interferences on the electric power supply line as it has special input and output filters. World leading DSP technology, with high speed DSP processor are adopted to guarantee system’s high stability and giving stable output power supply for all kinds of harsh load.

PERFECT APPLICAITON: Middle and large data center, Telecom, Finance, Traffic, Defense, Medical, Education, Energy, Manufacture, Industry, etc.

MAXIMUM RELIABILITY

MTBF >200,000h.
The advanced DSP technology appliance considerably improves reliability, since a reduction in electronic components lowers the likelihood of breakdowns. Digital control is provided by the microprocessor that, in the PV(II) series controls all the internal parameters, thus increasing reliability and performance. In parallel connections, digital control ensures balance of the currents, which generally change over time due to phenomena such as vibrations and temperature, between the UPS units and the exchange of information with no need for manual tuning. PV(II) has been designed so that it can be connected in parallel even after the installation of the first unit. The power availability can be increased thanks to various configurations available such as the parallel configuration, the Dual Bus function and the Dynamic Dual Bus system.

HIGH SPEED DSP PROCESSOR: Ensuring the operation more faster and more stable

OUTPUT 100% UNBALANCE LOAD

The UPS can accept 3phase 100% unbalance load to satisfy kinds of load configuration.

ECO function: under good power condition, UPS can work in ECO mode, efficiency reach 98%, green and energy saving;

UPS FOR INDUSTRIAL LOADS

PV(II) series with its strong overload capability, output galvanic isolation and low harmonic current distortion, is the ideal solution for industrial applications.

Thanks to the high battery current, PV(II) Series is suitable to work with large battery banks as it can guarantee recharging in 10 hours as recommended by the battery manufacturer.

OPERATING FLEXIBILITY:All power ratings of the PV(II) series can also be used as Frequency Converters 50 to 60 Hz and vice versa.

COLORFUL MULTIFUCTIONAL PANEL

The 7 inch colorful multifunctional panel allows easy and humanized operation of the UPS. It gives access to the most important parameters: status and alarms, control commands, input, output, battery measurements (power, current, voltage, frequency and temperature) and settings. The PV(II) series’ diagnostics system includes up to 128 alarms or messages allowing precise and detailed identification of any event.

Advanced Battery Management (ABM)

Optimal battery management includes:

• Periodic battery test, and automatically transfer between boost charging and float charging to extend battery lifespan
• Automatically adjusting the battery charging current according to battery capacity
• Recharge temperature compensation (optional)
• Remaining  back up time display

MAXIMUM SAFETY FOR PERSONNEL

The back feed protection device prevents any voltage back feed in the upstream distribution board, thus ensuring the safety of the maintenance personnel.

FULL FRONT ACCESS AND CONVENIENT CABLE CONNECTION

Full frontal access is for all power and electronic components, which reduces the floor space required and consequently reduces the installation costs.

Configured with top and bottom cable connection

PERFECT HUMAN-MACHINE COMMUNICATION

UPS Monitor software displays the most important information such as the input and output voltage, the load applied, the remaining back-up time, etc., in the form of bar graphs. The software is able to provide information even in the event of a failure, in support of the fault diagnostics. The UPS Monitor software can be used to program the automatic shutdown of all open systems in the event of a prolonged black out. PV(II) can also operate with a network agent for applications on LAN or WAN networks.

The UPS contains the following hardware interfaces:

• RS232 /RS485 interface,
• Dry contacts: battery low,battery discharge,bypass/breakdown
• EPO (Emergency Power Off) contact for UPS shutdown using the remote emergency button.
• SNMP card(optional)

ADVANCED PARALLEL

Maximum parallel up to 8 units and share the common battery pack.10-100kva parallel  can be with parallel card only ; 120kva-400kva, parallel card  with  weaver reactance and different capacity UPS can be also be parallel;

DYNAMIC DUAL BUS SYSTEM

Two independent systems set in Dual Bus Configuration can be merged together at any time for system expansion or maintenance. This provides a lot of flexibility in your installation in case of maintenance or when it is necessary to change the redundancy level of both systems.

EVENT LOG: 1000 historical events can be saved, which is easy for tracing UPS operation status and useful for maintenance
