Novastar BR460 Pro

NovaStar BR460 Pro — power supply and receiving card on one PCB

The BR460 Pro belongs to NovaStar's BR series, a family of integrated control boards combining the AC/DC power supply and the receiving card on a single board. At the back of a cabinet it replaces the usual "power supply unit + receiving card" pair with one item: less internal cabling, fewer connectors, fewer failure points, and depth saved.

It is the best compromise in the series: 32 A and the full image engine, in the standard 362 × 195 mm format that suits a 500 × 500 cabinet. It doubles the BR460 current for 37 g more and half a millimetre of thickness.

NovaStar BR460 Pro — technical analysis

Buying a BR board is not the same reasoning as buying a receiving card. What decides is the available DC current, because it caps the luminance the cabinet can hold at full white. Its 32 A under 4.2 V gives around 134 W, with a measured efficiency of 88 % at 240 Vac and 84 % at 100 Vac. That is double a standard BR460 in a near-identical footprint — which makes it the default proposal for a fine-pitch 500 × 500 cabinet.

It carries the full high-end feature set: 22bit+ multiplies grayscale resolution by 64, Image Booster covers Rec.709, DCI-P3 and Rec.2020, HDR10 complies with SMPTE ST 2084 and ST 2086, and Thermal Compensation 2.0 corrects cross banding from uneven dissipation. One-Click Sleep, driven from NovaLCT, shuts the screen down without going through the controller.

Three design points: the module connector format must match your panels exactly (connecteur JH1 60 broches, 5 groupes RGB parallèle); thermal derating means sizing cabinet ventilation accordingly; and since the board is both power supply and receiver, one failure takes out both — on a critical installation, plan spare stock accordingly.

On the "-1" references: NovaStar publishes a "-1" suffixed variant of this model whose published specifications are strictly identical: same dimensions to the tenth of a millimetre, same weight, same current, same load capacity. The manufacturer nowhere documents what the suffix means. We treat them as equivalent in performance and refer you to the cabinet manufacturer for mechanical compatibility.

• Fine-pitch 500 × 500 cabinets — the default proposal.
• HDR projects — HDR10 compliant with ST 2084 / ST 2086, and HLG.
• Cabinets with uneven dissipation — Thermal Compensation 2.0.
• Remotely managed installations — One-Click Sleep from NovaLCT.
• High-end panel manufacturing — one board instead of two, with no image compromise.

• Available current — 32 A nominal, 88 % efficiency at 240 Vac: double a BR460 in a near-identical footprint.
• Connectors — connecteur JH1 60 broches, 5 groupes RGB parallèle: check the exact match with your modules before ordering.
• Thermal — derating of 1.5 %/°C above 50 °C: cabinet ventilation determines the power actually available.
• Documentation caveat — the BR460-1 Pro datasheet states 512×384 in 10/12-bit where the BR460 Pro states 512×256. We keep the BR460 Pro value and have it confirmed by NovaStar.
• Single point of failure — power and reception on the same board: one failure takes out both, plan spare stock.
