Single Phase Output 10-40KVA Industrial Online UPS

Description

Industrial UPS are regarded as fully customized power supply systems for rugged environments and designed particularly to safeguard critical loads in industrial applications where voltage transients, created by degraded mains supply, can seriously damage both UPS and the critical load.

Application:
Petroleum, chemical industry, gas and power station and so on.

Key features:
• Adopt full digital control technology.
• Intelligent detection and monitoring function.
• Digitally control the static switch with zero switch.
• Full isolation between input and output.
• Super low output zero earth voltage.
• DC UPS isolated with utility power completely.
• Cubical design with power standard (customization).
• Multifunctional protection for over-voltage, under voltage, over current, short circuit and over temperature and so on.
• Large-screen LCD monitor with Chinese and English operation interface.
• Ultra-long 256 event record, user-friendly analysis and management to the situation of the power supply (touch screen display).
• Static bypass has a strong anti-overload capability.

Product advantages：

Adopting High-speed DSP Control

Adopting voltage and current stepping technology under CPU control, the rectifier of UPS has a soft start function. The input step is less than 15 seconds (adjustable), and the maximum impact current on the power grid does not exceed the rated current.

High Reliability

Built-in input transformer, output transformer, and bypass transformer realize complete Galvanic isolation. Instead of discrete IGBT and SCR components, we uses Modular IGBT and SCR in Rectifier and Inverter, bringing in extremely high reliability.

Advanced BMS

Intelligent battery management, comprehensive charge and discharge management of batteries, including charging voltage and current limiting, discharge cut-off voltage, extending battery lifetime 30%-50%.

Flexible customization

Industrial UPS can be customized according to the customer's environment, including input and output voltage, phase, frequency, battery voltage, charging current and IP level of the cabinet, etc.

Integrated design

The entire machine adopts a less fuse design, using circuit breakers, contactors, and electronic static switches. The circuit protection technology is advanced, greatly improving the reliability of the entire machine.

Strong Impact Ability

Adopting pulse-by-pulse technology to ensure that the maximum short-circuit current does not exceed the allowable range of single pulse short time IGBT, a pulse-by-pulse current limiting scheme is adopted.

Suitable for harsh environments

It can be applied in harsh environmental conditions such as dust, pests, high-temperature conditions, and earthquake areas to protect your important production processes and systems.

Parallel operation

Advanced distributed active parallel technology can realize parallel operation of 6PCS UPS units without the need for centralized bypass cabinet.

High compatibility

Compatible with Lead Acid (vented/sealed), NiCd (vented/gas recombination) batteries and lithium batteries.

FAQ：

What is a UPS?

A UPS is an electrical device that provides continuous, conditioned, uninterrupted power to acritical AC load. It also provides isolation between the input and the output. It consists of aRectifier/Battery Charger, Battery System, and inverter. The Battery Charger converts incoming commercial/utility AC power to DC power. This power is then supplied both to a Battery system and an inverter. The inverter then converts this DC power back into AC power which is fed to the critical load(s). The Battery is an emergency DC supply that is connected in parallel with the output of the Battery Charger, and supplies the DC power to the inverter (without any switching) in the event that the incoming commercial power is lost or outside of specified tolerances.

A true UPS is an on-line system, which means that under normal operating conditions, the power flow is through the Battery Charger, then through the inverter to the load. This differs from off-line, or stand-by systems, which are designed such that under normal conditions, power for the load is supplied directly from the commercial power source, NOT through the inverter. Depending on the design, and cost, the power may be conditioned by means of a Voltage Regulating Transformer or Power Conditioner placed in the power path between the commercial power source and the load. In an off-line or standby system, the inverter only supplies power to the load if the utility power fails. The Battery then picks up the inverter load for a finite period of time (typically 15–20 minutes). When the battery is depleted, the inverter will turn off, and the load will go down.

In order for a power supply to be considered a true UPS, it must accept three sources of power. The first source is the commercial, or utility, power that supplies AC power to the Battery Charger; the second is the Battery, which provides emergency DC power. The third source is a bypass, or alternate, AC source, which provides emergency AC power to the load if the inverter is unable to supply power, either because of an inverter failure, or a fault on the load. Under these conditions, the load would be automatically transferred to the bypass source via a static (electronic) transfer switch. The bypass source also supplies power in the event that the load is transferred manually from the inverter via a manual maintenance bypass switch.

A true on-line UPS is also referred to as a double conversion system. This means, as the name implies, that the power is converted twice. First it is converted from AC to DC at the Rectifier; then it is converted back from DC to AC at the inverter. Another common term is reverse transfer. This refers to the fact that the load, under certain conditions as described above (faults, equipment failure, or manual operation), is transferred back onto the commercial/utility power source.

Again, this differentiates it from an off-line system where, under normal operation, the load is powered from the utility source.

How do I size batteries for UPS applications?

UPS batteries are sized to provide emergency back-up power to the UPS in the event of a total AC blackout. While it is often a matter of convenience or personal preference, the length of back-up time required is primarily a function of the process being protected. It is also governed by the cost of the battery.

Since a UPS is utilized to provide continuous power to a process of one kind or another, the batteries should be sized to carry the load for as long as it takes to either complete the process, perform an orderly shut-down of the process, or bring a generator on-line to power the load. A UPS inverter converts DC power to AC power. The battery must be sized large enough to provide the DC input power (in kilowatts) for a fully loaded inverter for the specified length of time. The DC input power is determined by applying the load power factor, and inverter conversion efficiency to the inverter’s AC power rating.

Next, you must determine the DC bus voltage, and the corresponding number of battery cells. Then, you can determine the battery capacity per cell required for the load. (Note that a battery has a nominal voltage of 2 volts per cell. So, on a nominal 120 VDC bus, you will need 60 cells.) Then, using discharge data supplied by a battery manufacturer, you can determine the battery type and size required.

Following is a typical battery sizing example: 20kVA UPS (inverter) with a DC to AC conversion efficiency of 87%; a load power factor of 0.8, and a nominal 120 VDC bus.

Using discharge tables supplied by the battery manufacturer(s), select the type of battery that meets the above requirements of 0.307 kilowatts per cell.
