UPS ENERTRONIC I – 10 to 500 kVA

Maintaining operations safely – even in the event of grid disturbances or failures

Information and data technologies as well as increasingly automated production processes with complex data networking (Industry 4.0) require a reliable and trouble-free power supply.

For the supply of critical consumers, which require a voltage independent of disturbances of the public network, such as Petrochemical plants, Refineries, Power plants and substations, Process computers, Control rooms and SCADA systems should therefore use robust, uninterruptible power supplies (UPSs).

Maximum safety and economic efficiency

The UPS ENERTRONIC I complies with the highest UPS classification VFI SS 111 according to IEC / EN 62040-3 and stands for maximum safety and economic efficiency, based on the following features:

  • IGBT power semiconductors in the rectifier and inverter
  • Input power factor of ≥ 0.99
  • Mains feedback (THDi) < 5 %
  • Excellent control characteristics for high voltage stability, even with large load changes
  • Electronic changeover unit (EUE) and internal service bypass
  • Extensive reporting and monitoring functions
High short-circuit current

It is optionally possible to design the inverter for a three-phase short-circuit current of up to 4 x I-Nominal (ENERTRONIC I 3-3: 1ph 7 x IN, 3ph 4 x IN or ENERTRONIC I 3-1: 1ph 6 x IN). Depending on the power, a larger cabinet may be necessary.

Improvement in voltage and frequency quality

The static UPS system not only has the task of supplying the connected loads continuously and without interruption, but also achieves a significant improvement in voltage and frequency quality compared to the normal network.

Scalable and redundant

Up to 8 units of the ENERTRONIC I series can be connected in parallel for redundancy purposes or to increase power. It works with an active load sharing function in active and passive master mode.

UPS ENERTRONIC I – for enhanced safety

Due to the high load on the public power supply system caused by feedback from large consumers, switching on during peak consumption periods or lightning strikes, irregularities cannot be prevented. This results in voltage dips, overshoots and transients of the public grid voltage.

By placing your trust in a BENNING UPS system, you are choosing a high-quality product from one of the world’s leading manufacturers of AC and DC power supplies.

In normal operation, the consumer is supplied by the functional chain transformer, rectifier, inverter and output transformer.

Modern power electronics for economical operation

Rectifier

IGBT semiconductor rectifier bridge
The rectifier consists of an IGBT semiconductor rectifier bridge with power factor correction (power factor = 1), which converts the three-phase supply voltage into a regulated DC voltage to feed the inverter. At the same time, the connected battery is charged or always kept at the optimum state of charge in float charge mode. The rectifier is dimensioned in such a way that it can simultaneously supply the fully loaded inverter and, after a mains failure, recharge the discharged battery to approx. 95 % of the battery capacity in a time of approx. 12 hours.

Start-up delay with soft start
The rectifier has a start-up delay with soft start to ramp up the starting current after a mains failure. When parallel systems are switched on again, a series switch-on delay is automatically activated to limit the switch-on current to that of a single rectifier.

Charging current and voltage limitation
The rectifier has a charging current and voltage limitation according to the battery supplier’s specifications. A temperature-compensated charging characteristic can be integrated as an option.

Thyristor rectifier (SCR) optionally
Instead of the IGBT rectifier, a thyristor rectifier (SCR) can optionally be installed. This may require additional input filters depending on the targeted THDi.

Inverter

Sinusoidally optimised pulse width control
In the inverter, the DC voltage is converted into a single-phase voltage (ENERTRONIC I 3-1) or three-phase voltage (ENERTRONIC I 3-3) by means of sinusoidally optimised pulse width control via the IGBT semiconductors and the output isolating transformer.

Excellent dynamic behaviour if the load changes
Due to the high switching frequency in relation to the fundamental frequency as well as the optimal control of the pulse width, a very good efficiency and a very low distortion factor with non-linear load is achieved even in the partial load range. This also favours the excellent dynamic behaviour if the load changes.

Battery monitoring and automatic switchover
In the event of mains dips or failures, the battery connected to the DC input is automatically used to supply power without interruption. The discharge of the battery is reported. If the discharge threshold of the battery is not reached, the inverter switches off automatically and a message is displayed shortly before the end-of-discharge voltage is reached.

An automatic switchover of the loads to the bypass grid or a corresponding replacement system takes place when the supply by the inverter is no longer guaranteed within the specified tolerances.

Static bypass switch (SBS)

Various switching options
The SBS enables the loads to be switched to mains supply (bypass mains) without interruption – in compliance with the specified tolerances. The changeover can be triggered automatically by a control signal or manually by means of a button.

Safe operation and functionality
The monitoring is autonomous and prevents faulty operation of the system as well as any illogical switching functions of the SBS. For example, any uninterruptible switching, whether automatic or manual, is only possible if the voltage, frequency and phase position of the inverter are synchronised with the bypass grid. Mains frequency deviations that lie outside the specified tolerances cause a changeover block or, in the event of inverter failure, a changeover with interruption.

The SBS consists of a static, microprocessor-controlled and anti-parallel thyristor set in the mains bypass. automatically switches the connected loads to the mains without interruption in the event of a corresponding deviation of the output voltage from the set values. It automatically switches the load back to the inverter when an overload or short circuit has occurred and normal operation is available again.

Manual bypass

Internal manual bypass
The UPS system is equipped with an internal maintenance bypass (manual bypass) with a manually operated switch. The consumers are then supplied directly from the grid. With the option of an external manual bypass cabinet, the entire UPS can be de-energised, e.g. for recurring tests.

Can be connected in parallel with Group-Connector

Up to 8 units of the ENERTRONIC I series can be connected in parallel for redundancy purposes or to increase power. It works with an active load sharing function in active and passive master mode.

The Group Connector makes it possible to operate two UPS systems individually or in parallel. If half-load parallel operation is implemented with the aid of a coupling switch on two busbars, it is possible to read in the switch position during operation via an auxiliary contact.

When the tie breaker is closed, the load is distributed to both UPS systems – when the tie breaker is open, the UPS systems supply the respective connected rail. A secure supply to the load is thus ensured at all times.
