Industrial 48V Power Supply, 31.3A - 1500W

Core Advantages:

1,High Power Density

Features: Despite its high power output of 1500W, the dimensions are only 198*82*51mm, making it extremely compact.

Advantages: Significantly saves internal space, making it ideal for rack-mounted servers, communication equipment, and industrial automation equipment where space is critical.

2,High Efficiency and High Power Factor

Efficiency: Up to 92.5% (@230Vac), meaning low energy loss and low heat generation, contributing to improved overall energy efficiency and reliability while reducing operating costs.

3,Power Factor: PF > 0.98/100V, with built-in active PFC. This not only meets stringent global energy efficiency standards but also reduces harmonic pollution to the power grid, a hallmark of high-end power supplies.

Superior Reliability

4,MTBF: > 50,000 hours (at 25°C), meaning an exceptionally long mean time between failures (MTBF), providing robust product lifespan assurance.

Wide operating temperature range: -20°C to 60°C, capable of adapting to harsh industrial environments.

But there are some disadvantages,such as:

1,Ripple noise: 500mVp-p (approximately 150-200mVrms) may require extra attention for extremely sensitive precision instruments or RF circuits, but it is perfectly acceptable in most industrial and communication applications.

2,Short circuit/overvoltage protection lockout: While safe, it requires a 5-minute power-off wait for recovery, which may be inconvenient in certain applications requiring rapid reset. However, this is typically designed for severe faults.

3,Non-adjustable output: The output voltage is a fixed +48VDC and cannot be adjusted. This conforms to communication power standards (such as communication base stations, PoE switches, etc.), but limits applications requiring flexible voltage.

Q1,What is the over-load protection?

A1:The protection model is "Hiccup-like" automatic recovery. When overloaded between 120-180%, the power supply will intermittently attempt to restart, automatically returning to normal once the overload is relieved, avoiding manual intervention.

Q2:What is the Short circuit protection & output overvoltage protection?

A2:The system is locked and requires a 5-minute power outage to recover. This is a safety mechanism to prevent further damage from repeated restarts due to persistent faults (such as severe short circuits or internal component failures), and forces maintenance personnel to inspect the system.

Q3:What is the Input undervoltage protection & overtemperature protection?

A3:The protection model is Automatic recovery. The device automatically shuts down when the input voltage is too low or the temperature is too high, and automatically restarts when conditions return to normal, addressing temporary anomalies.

Q4:When will the order be shipped and delivered?

A4:For samples,7-10 working days after you made the payment;15-20 working days for the mass production of the power supply.

Q5:Are your products suitable for wholesale and retail?

A5:YES,the power supply is suitable for wholesale and retail.

Q6:Can you provide me with the service manual for the power supply?

A6:Sorry,we can provide the power supply specification.
