     This is a dedicated switching power supply tailored for specific stage lighting equipment, rather than a general-purpose power supply. Its dual-output design cleverly separates the power supply needs of different loads: V1 is responsible for high-power core components (such as LED light sources or discharge bulbs), while V2 is responsible for the control and motion system.

   1. Dual-Output Design - Core Architecture Analysis

   V1 Channel (+52VDC, 28A, 1456W):

Application Speculation: This is the main power channel, most likely used to drive the main light source of the luminaire.

For LED Luminaires: Modern high-power stage LED lights require high voltage and high current to drive multiple strings of high-brightness LEDs. The 52V/28A configuration is ideal for driving one or a group of high-power LEDs to achieve high brightness and rich colors (RGBW).

For Traditional Discharge Lamps: Although the discharge bulb itself requires several KV of high voltage for triggering, its electronic ballast input typically requires a stable high-voltage DC power supply. 1456W of power is more than sufficient to support gas discharge bulbs in the 575W~1200W range.

   Conclusion: V1 channel is the "heart" of the luminaire, determining its maximum output brightness and color performance.

    V2 Channel (+36VDC, 9.7A, 349.2W):

Application Speculation: This is the auxiliary power channel, primarily used to drive the control and motion systems of the lighting fixtures.

Stepper/Servo Motors: Stage moving head lights require precise angle and position control. Their internal Pan (horizontal rotation) and Tilt (vertical tilt) motors are typically stepper or servo motors. 36V is ideal for powering the drivers of these motors, providing fast, smooth, and powerful movement.

Control Circuits, Fans, Stepper Motors, etc.: This power supply also powers the main control board (CPU), DMX512 receiver chip, color wheel, pattern wheel, focus motor, and other auxiliary components. 349W of power provides ample energy for these complex mechanisms.

   2. Output Accuracy, Regulation, and Stability Analysis

V1 Channel (Accuracy ±2%, Line Regulation ±0.1%, Negative Regulation ±2%):

Analysis: Excellent performance. A ±0.1% line regulation means that fluctuations in mains voltage have minimal impact on the output voltage. A ±2% load regulation means that the output voltage remains remarkably stable regardless of whether the LED is dimly lit or fully lit.

Impact on Lighting: This is crucial for the main light source.

LED Light Source: Stable voltage ensures that the LED's color (color temperature, color coordinates) does not drift, avoiding visible flickering or uneven brightness. This is especially important for demanding applications such as live television broadcasts and film shooting.

Discharge Bulb Light Source: Stable power supply is a prerequisite for the stable operation of the electronic ballast, ensuring bulb life and stable light output.

   V2 Channel (Accuracy ±6%, Line Regulation ±0.5%, Negative Regulation ±2%):

Analysis: Performance parameters are significantly lower than V1 channel, especially output accuracy (±6%) and line regulation (±0.5%). This usually means that the power supply for this channel is cheaper or uses a different topology (such as a non-isolated Buck circuit).

Impact on Lighting: This is acceptable for motor drive systems. Stepper motors and servo motors are not inherently sensitive to absolute voltage accuracy; their drivers have internal voltage regulation and current control circuits. As long as the voltage is within a reasonable range (e.g., 36V±6% ≈ 33.8V ~ 38.2V), the motor will operate normally. The ±2% load regulation ensures that the voltage does not fluctuate drastically under dynamic loads such as motor start-up and stop, ensuring smooth movement.

   In one word,this power supply is a typical stage lighting power supply with a clear design goal. Through a dual-path architecture with a clear distinction between primary and secondary paths, it ensures the stability of the core light source while also meeting the power requirements of the motion system, achieving a good balance in terms of cost. It is ideal for mid-to-high-end moving head lights, beam lights, or pattern lights. For lighting manufacturers, the key is to design robust control and drive circuits based on the characteristics of the V2 path to fully utilize the power supply's performance.

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.
