Uninterruptible power supplies typically store electrical energy in lead-acid batteries. Temperatures, such as those found in control cabinets, can shorten the battery's lifespan. Not so with the innovative DC UPS from SITOP. Long-life capacitors eliminate the need for battery replacement, allowing the maintenance-free UPS to pay for itself in a short time. And since no hydrogen is emitted, the control cabinet does not need to be ventilated. Short charging times also ensure quick availability after a power outage.

The advantages at a glance:

• Modular cascading for DIN rail mounting: Base unit SITOP UPS500S 24 V / 15 A with integrated energy storage of 2.5 or 5 kW, combinable with up to 3 expansion modules UPS 501S (5 kW)
• Long-lasting capacitors eliminate battery replacement: After 8 years at 50 °C ambient temperature, the UPS500 still retains 80% of its nominal capacity
• Completely maintenance-free
• No ventilation of the installation site required
• Fast restoration of buffer readiness
• Safe shutdown and correct restart of SIMATIC PCs. The connection and commissioning of a UPS with over 3.5 kVA must be clarified in advance with the local electricity provider. The connection must be made by a qualified electrician.
