- Часто задаваемые вопросы
Q1: What is the difference between 8862850000 и 8710620000?
А: Both are order numbers for CP DM 10. 8710620000 is the original part number, пока 8862850000 is the transitional replacement number; the product itself is identical.
Q2: Can PRO DM 10 directly replace CP DM 10?
А: Fully compatible in physical dimensions, electrical parameters and wiring; additionally equipped with over-temperature protection.
Q3: How to select power supply capacity in redundant mode?
А: Each power supply should be sized no less than the total load power, ensuring single power supply can carry full load independently. The diode module only performs switching and does not amplify power.

Physically compatible for direct swap, no changes to terminals and wiring;
General redundancy pick DM, high-efficiency current sharing pick RM.
- Replacement Implementation Key Points
- Direct Interchange: PRO DM series is fully compatible with corresponding CP DM models in dimensions and terminal layout for direct replacement.
- Wiring Note: No need to modify power input (++/–) and load output (++/–) проводка; tightening torque 0.5~0.6Nm.
- Function Setting: Over-temperature protection is enabled by default on PRO DM, no extra configuration required.
