Power supply PS-E

Intrinsically safe power supply PS-E (PS-E/A) is designed for external power supply of the main electronics (volume corrector part / data logger part) of these devices:

  • ELCORplus
  • ELCORplus indexer
  • DATCOMplus

The PS-E (PS-E/A) intrinsically safe power supply is supplied with a DC voltage of 12 V. The power supply is inbuilt in a plastic box and it is intended for mounting onto a 35 mm DIN rail.

From the point of view of use in potentially explosive atmospheres, the power supply is designed as an associated apparatus, which must be installed outside the hazardous area.

To be externally powered, the corrector/data logger must be equipped with the S3-PWR1 plug-in module.

Remark:
The PS-E (PS-E/A) power supply is not designed to power an integrated modem (if fitted).


Basic features:

  • Intrinsically safe power supply for ELCORplus volume corrector and DATCOMplus data logger
  • Supplied in 35 mm DIN rail mounting

  • Power supply voltage 12 V DC

  • No-load output voltage 4,6 V DC

  • Operating temperature -40 až +70 °C

The use of an external power supply is recommended:

  • If the volume corrector/data logger operating mode is set to have a higher battery consumption and thus shorten its battery life (eg on-line communication)

The external power supply must be used:

  • When using the S0-EXT1 module with HF NAMUR pulse input
  • When using a NAMUR encoder with a measurement period of less than 1 min

Available variants:

  • PS-E - basic PS-E power supply is designed for systems whose power is derived from mains voltage (Um = 250V). The PS-E can be powered, for example, from a non-backed-up power supply or from a battery backed-up power supply with an AC charger
  • PS-E/A - The PS-E/A power supply has reduced its own power consumption compared to the basic design. Its use is suitable for battery-powered systems which can be recharged via solar panels (Um = 60V)
