Buffer modules - bridging power failures without a battery

With the maintenance-free buffer modules from FEAS, you protect your systems from brief power failures and peak loads

These buffer modules of the SSE series from FEAS are suitable for bridging short-term mains failures, peak loads or switching operations. The required energy is stored in internal super capacitors. Thus, these uninterruptible power supplies (UPS) are absolutely maintenance-free. A rechargeable battery is not installed. Fully encapsulated in an aluminium housing, the capacitor-based buffer module is characterised by vibration resistance, industrial and tropical suitability.

Note:
UPS with battery for longer downtimes can be found under the product category "DC UPS - with accu".

Buffer modules - for a wide range of applications

Choose a buffer module that suits your application:
► Output voltage 12VDC, 24VDC, 30VDC, 48VDC, 60VDC or 70VDC
► with AC or DC input / with or without integrated power supply unit
► adjustable buffer voltage
► Boost function up to 200%
► with typical buffer times between 4s and 30min
► Remote monitoring (power failure, state of charge, temperature, overload)
► Installation on DIN rail or wall mounting

Buffer modules - how they work

The buffer module (DC UPS with capacitor) is connected in parallel directly into the regulated DC circuit at any point or used for selective protection of critical loads. As long as the DC power supply provides the voltage, this buffer module (UPS) stores energy in buffer capacitors (super or ultra capacitors). If the mains voltage fails, the buffer module takes over the load current for a certain time. This allows, for example, processes to be terminated in a defined manner or process data to be saved.

Buffer modules - output voltage 12VDC, 24VDC, 30VDC, 48VDC, 60VDC, 70VDC

First select the required output voltage of your buffer module (12VDC, 24VDC, 30VDC, 48VDC, 60VDC or 70VDC). You will get a list of all buffer modules from FEAS.
