Expert Questions & Answers

• What does "summable" mean for this power supply?

The 140CPS21400C can be paralleled with other units to increase total current capacity. This allows system expansion without replacing the existing power supply.

• How do I calculate heat dissipation for my system?

Use formula: 6W + (1.8 × output current in amps). For example, at 5A output: 6 + (1.8 × 5) = 15W. Ensure adequate panel ventilation for heat removal.

• What circuit breaker size should I use for input power?

Use a 10A circuit breaker to handle the 25A inrush current. The internal 5A slow-blow fuse provides additional protection for the module itself.

• Can this power supply operate in redundant configurations?

Yes, its summable design supports redundant parallel operation. Use diode isolation modules for proper redundant system implementation.

• What happens during a brownout condition?

The wide input range (20-30VDC) allows operation during voltage dips. The module maintains regulated output down to 20V input, providing brownout protection.
