Ropam PSR-ECO-2012 Intelligent, buffer type supervised AC-DC power supply

Ropam PSR-ECO-2012 Intelligent, buffer type supervised AC-DC power supply

The ECO series buffer power supply with an efficiency of up to 91% and which is perfect for installations low-current.
PSR-ECO power supplies are based on newest IC's (SMPS). These solutions eliminates power losses sources: transformer, rectifier, voltage regulator. PSR-ECO-5012 integrates three functions in one design: regulated power supply, battery charger, UPS for 12VDC or 24VDC - see version.

AC/DC functions and parameters, energy conversion block

• high energy efficiency, typicaly 88% in full operating range (88%-91%)
• increased galvanic separation PRI/SEC: 3,5kV (other power supplies typically: 1,5kV)
• output power 50W in full range according to II'nd environmental class
• max power 20W, power supply internally balanced
• 12VDC low ripple and low noise power supply
• output voltage regulation
• electronic protection with autorecovery: overcurrent OCP, short circuit SCP, overheat OHP, over voltage OVP, undervolatge UVP
• high quality power components
• passive convection cooling system
• 100% tested with and without load
• SMT & THT mount
• high EMC & ESD immunity for industrial type devices and low emission like for home applications
• II'nd environmental classi, without PE circuit
• DIN 2M (ABS, UL94 V-0) casing and dedicated wall casings

Battery charger functions and parameters

• constant current, constant voltage charging system
• temperature autocompensation +/- 3,3 [mV/°C/cell] regards to 20°C
• autonomic, electronic protections: overcurrent OCP, short circuit SCP, undervoltage UVP, reverse polarity (RPP)
• dynamic test and diagnosis of battery during normal work (with load)
• overcharge protection: advanced algorythm that measures charge delivered to battery, if Qbat>Qmax and no const. voltage charging enabled, then controller will turn on fail indicator, but leave battery as backup power supply
• SLA and AGM 12V battery support

Power supply status, in system configuration

• construction and functions follows PN-EN 50131-6, grade 2 or 3, A type
• microcontroller supervised working state and functions
• basic parameters measure: voltages, currents, temperature
• test and calibration 100% power supplies during manufacturing process
• technical outputs: AC state, battery state, other failures
• supervision and communication with OptimaGSM, BasicGSM 2, MultiGSM 2
• optical signalization of power supply state and failures (codes)
