SIL 3 certified, 24 Vdc modular power supply is suitable for installation in safe area and Zone/division 2.
Designed for 100% availability and high Integrity applications;
built-in load sharing in both DIN-rail and rack mounted solutions
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.
SIL rated power supply
Zone 2 Div. 2 Installation
Current Sharing Bus (No additional diodes)
Effincecy greater than 93% @230 Vac and full output capacity
Under Voltage and Over Voltage protection
Din rail mounting
Highly regulated 24Vdc, 20A output
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
SIL rated power supply
Zone 2 Div. 2 Installation
Up to 50 redundant configurations
Internal Current Sharing (No additional diodes)
Redundant internal ventilation
Under Voltage and Over Voltage protection
Wall or front cabinet mounting
DNV marine type approval
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.
