MARATON low voltage power supply system for hazardous HE
The high density very powerful and compact low-voltage floating power supply system MARATON possesses in a 3U high box 12 independent channels of 300W each. In parallel operation the output power per channel can be boosted to 600W / 900W /1200W... with 6 / 4 / 3... channel utilization.
Dynamic behavior adjustable by internal jumper (long-short sensed distances to loads). .
- up to 12 independent, potential free outputs, total up to 3 kW DC output power (nom. 385VDC inp.), 3,6kW water cooled
- Fully controlled, adjustable trip levels
- Adjustable voltages, current limits and OVP-trip levels
- Extremely low noise and ripple
- CE conform EN 50 081/82 part 2 or 1, safety in accordance with EN 60 950
- 385V DC input for low cross section cabling
- VME compatible remote monitoring and control module for 12 channels with Ethernet (TCP/IP) interface (for Standard Environment)
- Water cooled (recommended) or by forced air

M T B F, cooled by:
Water, 30°C inflow:
Forced Air, 30°C entrance: |
Conditions: 3kW DC output with 80% efficiency (600W internal power dissipation: WORST CASE)
ca. 120,000 h , put through > 50l/h for <10°C DT of cooling water. Minimum differential pressure >0.5 bar, abs. max. pressure <15bar
ca. 90,000 h , put through > 153m3/h for <15°C DT of cooling air, ambient air pressure 1 bar. Adequate airflow isroughlyy 1,4m/s.
Values for air cooled units are valid for new ones. Abrasive dust, corrosion, etc. can limiting the heat transfer to the cooling air during lifetime. Higher operating temperature is the consequence.
Increasing of internaltemperater at the most critical points of 10°C will reduce the MTBF by 50% Lower operationtemperaturess will increase the MTBFaccordinglyy, independent of cooling medium. |
