Exloc Instruments Expand the PSX1200 Series Power Supplies by GM International

Earlier in the year, Exloc and GM International introduced the PSX1200 Series power supplies to the market.

 The original PSX1200 series are housed in stainless steel (AISI 304) and can be supplied in Wall, DIN-Rail, or rack mounting versions, each providing 24Vdc, 50 A output. (Read More)

Their stand alone or modular configuration make them extremely versatile and ideal for a wide range of applications on site.
The range is now being expanded to include the PSW1230, also a stainless steel AISI 304 unit but providing a 24Vdc, 30A output to facilitate a more scalable overall solution.

The units can be paralleled, with load sharing circuits, which distribute current load equally to each power supply to increase reliability and reduce internal power dissipation.
The Supplies all accepts AC power sources from 100 to 264Vac.

Each PSU has been designed to provide the greatest levels of availability and safety for high integrity and safety critical applications.

Safety

• The PSX1200 series provides three independent overvoltage protections: 1 voltage limiting loop at 30Vdc and 1+1 crowbars at 31 Vdc.
• The power supply has under and over voltage alarm monitoring as standard and has high load fuse breaking capacity to ensure that in the event that one load attached to the power supply fails, others are not affected.
• Units are SIL2/SIL3 according to IEC61508:2010 Ed. 2.
• The PSX1200 range have been specifically designed for installation in Zone 2 / Div. 2 hazardous locations and carry ATEX and IECEx Certifications.

Availability

• Each power supply has two universal AC input lines and fully redundant options, all available with load sharing.

Features

• The supplies also benefit from Active Ideal Diode circuitry to provide lower internal power dissipation and greater operating efficiency.
• Tropicalisation of components offers higher resistance to heat and humidity.
• Operating temperature limits: -40 to +70°C de-rated linearly 65-70% load above 50°C.

Performance

• Each PSX1200 power supply can provide up to 1200 W per single unit or up to 6 units can provide 3600 W (fully redundant) if mounted within the PPS1250 19” rack system.
• The PSX1200 has better than 87% efficiency with 0.98 Power Factor Correction.
• The PSX1200 series is designed for fast output dynamic response.

The PPS1250 Rack Mounting System

Hot Swap Plug-ins:

When using racks configured for Hot Swapping, each PS series power supply module can be placed in Zone 2/Div. 2 Hazardous Locations without having to monitor the hazardous gas present and without disturbing Power Supply operations.
Diagnostic:

A plugin module (PSO1250) dedicated to monitoring all diagnostic functions of each power supply can be installed in the last rack slot and operated through a front panel touch screen LCD colour display which indicates input/output voltage, current and power, input line frequency, output current sharing percentage, internal temperature, alarm status.

RS485 Modbus output provides full diagnostic and status conditions.

PSO1250 presence or fault does not affect PSS1250 operation and functional safety application.

EMC:

Fully compliant with CE marking applicable requirements.
