POWER SUPPLIES

STRENGTHS

• Smaller foot print: very compact design
• Flexibility: wall/rack/DIN-rail types
• Environmental condition: extended temperature range, -40°C ÷ +70°C
• G3 coating, tested for marine application (EMC, vibration, etc.)
• Zone 2 installation: reduced cable distance
• Improved safety, integrity and reliability: SIL 3 certified by third party
• High efficiency, reduced bulk power & dissipation: builtin intelligent load sharing
• Easier Installation: no external OR-ing diodes needed for redundancy
• Zero Downtime: built-in redundancy, operation under output short-circuit condition, automatic load sharing of 2 or more modules
• Reduced maintenance cost: hot swapping, also in zone 2 (PSS1250)
• Guaranteed fault isolation: short circuit protection
• Easier troubleshooting: local and remote (optional Modbus) diagnostic

PSD1220 STRUCTURE

CHARACTERISTICS

Easy Wiring
The load current sharing functionality can be achieved by a simple daisy chain. The bus is capable to ballance the loads among the units and ensure stability.

Easy Mounting
Install the power supply directly on a din rail bar and quickly plug the cable with the sping terminal blocks version.

Wide Operating Range
The PSD1220 accepts AC power input sources from 110V to 240V and operates from -40 to +60°C with minimum derating.

PSS1250 STRUCTURE

CHARACTERISTICS

Short circuit proof
If the PSS1250 detects a short circuit on a load, it delivers a high peak of current to the circuit breaker or protective fuse of the specific load. This does not affect or interrupt the entire operations.

Locan and Remote diagnostic
PSO1250 diagnostic modules with LCD color touchscreen provide a full overview of the healt of the installation. The Modbus RTU comunication guarantees a remote control of the application

Hot Swapping and Easy Maintenance
The Hot Swapping Controller circuits disconnects the AC line on each PSM1250 in case it is necessary to connect or disconnct a module. This can be done during the normal operations withour causing harm to both the installation and the operator.  No additional certified circuit breakers required

PSW1250 STRUCTURE

CHARACTERISTICS

Alarm Monitoring
3 redundant over voltage protection to ensure the safety and continuos monitoring of your application. Both the under voltage and over voltage conditions are signaled by a relay alarm.

Reduced Power Dissipation
The internal ideal diode replace the standard external shotcky diode tipically used in parallel configurations, enhancing efficency and contains wiring and maintenance costs.

Flexible and Resilient
The internal cooling system self-regulates depending on ambient temperature and output power. The tropicalicazation ensure protection and durability in hars environment for a long period of time.
