PRODUCT DESCRIPTION
6EP1437-3BA10 Three Phase Power Supply
Siemens 6EP1437-3BA10 is a SITOP PSU8200 stabilized power supply for three-phase industrial mains. It converts the specified AC input into a regulated 24 V DC supply for automation loads in production and process equipment.
The unit delivers 40 A with a rated output power of 960 W, and its output can be adjusted from 24 to 28.8 V. Screw terminals provide the mains, protective-earth and DC connections, while a normally open relay reports the 24 V OK state. Selectable overload behaviour and short-duration reserve current support the documented load arrangement.

ACTUAL APPLICATIONS
Application context for 6EP1437-3BA10
6EP1437-3BA10 supplies regulated DC power in automotive, food and chemical production. Suitability depends on the three-phase mains, connected load and cooling conditions. The 40 A rating applies within its documented operating range; ambient temperatures above 60 ℃ require current derating.

SYSTEM INTEGRATION
Integrate 6EP1437-3BA10 three phase power supply
Integrate 6EP1437-3BA10 as the specified three-phase SITOP PSU8200 source for regulated 24 V DC loads. Compare the 400–500 V nominal mains rating and the permitted 320–575 V input range with the actual supply.
Check the 40 A load, conductor arrangement and output-voltage setting against the verified power design. The 24 V OK relay is rated at 60 V DC and 0.3 A; maintain the documented isolation and protective-earth connection.
Follow the complete power-supply instructions for mounting, connection and acceptance. Check output voltage under the intended load, the relay indication and thermal conditions, including derating above 60 ℃, before releasing the installation.
Features:
- Nominal input mains: 3-phase AC; 400–500 V
- Permitted AC input: 320–575 V
- Line frequency range: 47–63 Hz
The 6EP1437-3BA10 three phase power supply requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify 6EP1437-3BA10 three phase power supply
Match the full 6EP1437-3BA10 designation and its three-phase input to the installed supply. The officially listed successor is 6EP3437-8SB00-0AY0; compare its dimensions, terminals and electrical behaviour before adopting it.
Record input phases, protective earth, output polarity, set voltage and any parallel arrangement before removal. Confirm the connected load and the selected short-circuit response rather than selecting a replacement by current rating alone.
After the controlled replacement, verify regulated DC output and the 24 V OK signal. Test the specified load response and check ventilation and temperature limits, then retain the accepted settings with the machine power documentation.
Features:
- Nominal input mains: 3-phase AC; 400–500 V
- Permitted AC input: 320–575 V
- Line frequency range: 47–63 Hz
The 6EP1437-3BA10 three phase power supply requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6EP1437-3BA10
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What three-phase mains range is accepted by this PSU8200?
6EP1437-3BA10 has a nominal 400–500 V AC input and permits 320–575 V AC at 47–63 Hz. -
How far can the stabilized 24 V output be adjusted?
The output can be set from 24 to 28.8 V. The published maximum output power remains 960 W. -
When must the 40 A supply current be reduced?
Above 60 ℃, apply the specified derating of 3.75% per kelvin. The documented ambient operating range extends to 70 ℃. -
What rating applies to the DC OK signalling contact?
The normally open 24 V OK relay contact is rated at 60 V DC and 0.3 A; it is separate from the main 40 A output. -
Does the overload reserve support continuous excess current?
No. The stated 150% output-current reserve is limited to up to 5 seconds per minute and must not be treated as a continuous rating. -
Is the listed successor a replacement without further checking?
Siemens identifies 6EP3437-8SB00-0AY0 as the successor. Confirm the complete electrical, mounting and connection requirements before exchanging the installed supply. -
Which mains and load details belong in a 40 A supply enquiry?
Provide the 6EP1437-3BA10 label, actual three-phase mains voltage, connected DC load, current output setting and any parallel-supply arrangement, together with quantity. -
What should receiving inspection confirm on a three-phase PSU8200?
Compare the complete article label, L1/L2/L3/PE terminals, DC output connections and DC OK contact arrangement, and inspect physical condition before energising the supplied unit.
