Kiloview 300W power supply module for 3RU-32H rackmount

The Kiloview PU03-300W (often cataloged as KIL-PU03-300W) is an industrial-grade, hot-swappable 300-Watt power supply module engineered specifically for the Kiloview Cradle Series RU03 and RU03S 3RU rackmount mainframes.

This module serves either as the primary engine inside a standard RU03 chassis or as the secondary, matching module required to establish a true dual-redundant power configuration in mission-critical broadcast environments.

Core Engineering and Structural Features

• Hot-Swappable Slide-In Architecture: The module is designed with a heavy-duty alignment rail and a high-tolerance rear blade connector. This allows broadcast engineers to slide the power supply straight into the rear of an active RU03/RU03S chassis and lock it into place using integrated thumb screws without interrupting the operation of any active video encoder or decoder cards inside the frame.

• Active Load-Sharing Capability: When paired inside an RU03S or an upgraded RU03 chassis, two PU03-300W modules communicate over the backplane to split the frame's electrical load evenly (running at roughly 50% capacity each). This extends the overall lifespan of the internal capacitors by minimizing heat generation on a single board.

• Zero-Latency Failure Handover: If one power grid fails or a module suffers an internal fault, the secondary PU03-300W instantly assumes 100% of the electrical load. The switchover occurs in less than a millisecond, preventing voltage drops that could cause codec cards to drop frames, glitch, or reboot.

• Dedicated Smart Cooling Fan: The module incorporates its own independent, high-velocity internal cooling fan. Rather than relying solely on the chassis exhaust, this localized fan draws cool air straight across its heavy-duty transformers and outputs it through the rear grille, preventing localized hotspots in packed server racks.

• Comprehensive Electrical Protection Circuits: To safeguard expensive downstream multi-channel processing cards, the module features built-in hardware protection safeguards, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP).

💡 Operational System Tips for the PU03-300W

The True Redundancy Grid Rule: Installing a secondary PU03-300W module into your rack frame only protects you from a venue-wide blackout if it is wired correctly. Never plug both power modules into the same power strip or the same localized circuit breaker loop. To achieve true broadcast-grade redundancy, connect the first power module to your primary building grid (or a local Uninterruptible Power Supply) and route the second AC cord to an entirely independent backup circuit breaker or generator line.

• Monitoring the Hardware Status LEDs: The rear plate of the PU03-300W features a dedicated status LED next to the AC receptacle. A solid green light indicates that incoming AC power is clean and the DC output rail is healthy. If you are conducting a routine maintenance check in a loud control room and notice an unlit or flashing amber LED, the module has triggered an internal protection circuit or lost its input line, signaling that it needs immediate inspection or a hot-swap replacement.
