• Technology: Overload- and no-load-proof, short-circuit-proof
• Protection class: Tropicalised due to full cast resin encapsulation
• Type of installation: wall mounting or top-hat rail

DC UPS & Buffer Modules

DC UPS - for a wide range of applications

Choose a DC UPS to suit your application:
 

• Output voltage: 12VDC or 24 VDC or a unit with both options
• AC or DC input / with or without integrated power supply unit
• Optionally also with 3-phase input or as low voltage version (LV)
• Buffer times from 30min - 270min
• Optionally with high-temperature batteries up to 70°C
• Optionally with RS-232 / RS-485 interface
• NiMH or lead-gel batteries
• Terminal version or cable version
• Mounting on top-hat rail or wall mounting

Buffer modules - for a wide range of applications

Choose a buffer module that suits your application:

• Output voltage: 12VDC, 24VDC or 48VDC
• AC or DC input / with or without integrated power supply unit
• Adjustable buffer voltage
• Boost function up to 200
• Buffer times between 30s and 110s
• Remote monitoring (mains failure, state of charge, temperature, overload)
• Mounting on top-hat rail or wall mounting

EMC filter - radio interference filter

Choose an EMC filter for your:

• Supply with DC voltage or AC voltage (1-phase, 3-phase, 3-phase+neutral)
  1-stage or 2-stage interference suppression
  Optimised against symmetrical or asymmetrical interference or interference in the lower frequency range
  With different enclosure types (fully encapsulated aluminium enclosure or self-extinguishing polycarbonate enclosure, optimised for sub-distribution boards, ...).

Redundancy modules

Redundancy modules for the following voltage ranges:
 

• 5,0 VDC - 50 VDC
• 11,5 VDC - 50 VDC
• 40,0 VDC - 120 VDC

Choose a redundancy module that suits your application, optionally with:

• Terminal or cable connection
• LED display and signalling contact
• Thermal overload protection
• Main circuit: input 2-pole, output 1-pole or input and output 3-pole
• Potentiometer for setting the voltage error limit at the inputs

All FEAS redundancy modules are characterised, among other things, by their simple mounting on DIN rails, integrated heat sinks, reverse polarity protection at the output, vibration resistance and suitability for tropical conditions.

Transformers & Function Modules

Transformers

Choose a transformer to supply your appliances with 12VAC or 24VAC
 

Input voltage: 115VAC or 230VAC
Output voltage: 12VAC or 24VAC (short-circuit proof)
Features: long life and relatively high efficiency (>93%)

Thanks to their robust construction, encapsulated in a stable aluminium housing, the transformers are particularly suitable for use in harsh industrial environments or, for example, in shipbuilding.

Function modules

Designed for:

• Setpoint distributor
• Motor standstill indicator
• Soft start

The high-quality function modules from FEAS are installed in a self-extinguishing polycarbonate housing and are mounted directly on the top-hat rail.
