A UPS (uninterruptible power supply) is a device that ensures power supply to connected devices in the event of power outages or voltage fluctuations. It is primarily used to protect IT systems, networks, automation, and other sensitive electronic devices (e.g., medical technology) to prevent data loss and hardware damage.

A UPS provides immediate power without interruption, via batteries, but only for a limited time. A generator, on the other hand, starts automatically (with a short delay) in the event of a power outage and can supply energy for extended periods as it runs on diesel. Both systems are often used in combination to achieve higher availability.

The bridging time of a UPS depends on the battery capacity and the connected load. Typically, it ranges from a few minutes to several hours. The goal is to have enough time to shut down systems in a controlled manner or to start an emergency power generator.

There are three main types:
- Offline or standby UPS (for simple applications, Class 3)

- Line-interactive UPS (for medium requirements with voltage regulation, Class 2)

- Online UPS (double converter technology for maximum safety and constant power quality, Class 1)At ALLTRONIC, we only offer Class 1 systems.

Regular maintenance is crucial for reliability. As a rule, a UPS should be checked at least once a year. Batteries must be replaced depending on the type and use. In addition, functional tests and visual inspections should be carried out regularly.

A battery system is an energy storage unit that stores electrical energy in the form of chemical energy and releases it when needed. Battery systems are used in combination with UPS systems and/or emergency generators, because only with a functioning battery and UPS can the emergency power technology supply without interruption.

The most common battery types are:

• Lead-acid batteries (classic and cost-effective)
• VRLA batteries (low maintenance, e.g., AGM or gel)
• Lithium-ion batteries (high energy density and long lifespan)
  The selection depends on requirements such as space, lifespan, and budget.

The lifespan varies depending on the battery type, usage, and environment.

• Lead-acid batteries: approx. 3–10 years
• Lithium-ion batteries: often 10–15 years or more
  Regular maintenance and optimal operating conditions significantly extend the lifespan.

Maintenance includes:

• Regular visual inspections
• Checking voltage and capacity
• Cleaning contacts
• Internal resistance measurements
• Performance tests
• Temperature monitoring
  Depending on the battery type, the maintenance effort can vary (maintenance-free vs. high-maintenance).

Important points include:

• Adequate ventilation (especially for lead-acid batteries due to gas formation)
• Protection against overcharging and deep discharging
• Adherence to temperature limits
• Professional installation and regular inspection
  This ensures safe and reliable operation.

A diesel generator is a power generator that converts the mechanical energy of a diesel engine into electrical energy. It is often used as an emergency power supply in hospitals, data centers, industrial plants, or on construction sites.

A diesel generator usually starts within a few seconds (approx. 3–10 seconds).

The running time depends mainly on the size of the fuel tank and the consumption. Our diesel generators are designed for 24/7 operation.

Diesel generators should be serviced regularly, typically:

• After a fixed number of operating hours (e.g., every 250–500 hours)
• At least once a year
  Maintenance work includes oil changes, filter replacement, battery checks, and functional tests.

Performance is influenced by factors such as:

• Ambient temperature and altitude
• Fuel quality
• Generator maintenance status
• Load profile (constant or variable load)
  Correct sizing is crucial for reliable operation.
