The bus technology from products such as computers, cars, passenger-carrying aircraft but not indispensable even for remote control systems. Gradually there are more accessories such as servos, sensors, etc. for bus systems. Simultaneously, the development of peripherals such as servos etc. goes increasingly towards HV (high-voltage 2 S Lipo).

Futaba is the S-Bus and S-Bus II system pioneer in this technology. But for some time now also provide Graupner Hott, MPX M-Link and the FrSky X-Series receiver next to the sum signal to a digital bus.

That was the reason to conceive the PMS Big Bus for us. The PMS Big Bus has been consistently designed components for bus systems and HV.

Since the most common cause of defects in battery backer is damage caused by a short circuit or an overload, we have come up with something new here. The PMS Big Bus has for all servo outputs its own "self-healing" fuse. This triggers a short circuit or overload without a persistent defect remains. At the latest after the power cycle all functions are restored. This is also a total failure of the system in case of short circuit of a servo or a lead is excluded. We see this novelty as another very important contribution to secure electricity supply.

Important status indicators are displayed on the PMS Big Bus built LEDs. About optional control - but LEDs it is possible these status displays outside of the hull, or for example, View in the cockpit allow.

By eliminating unnecessary settings and the model is not visible displays, we were in the new PMS Big Bus correspond to the request of our customers for an inexpensive power switch with a very high safety standard.

The power management systems are being developed by a team of engineers active in aeromodelling and provide in conjunction with high-quality RC components maximum reliability in the receiving system area. They are manufactured in industrial quality in Germany. All components are designed in high quality and for industrial use.

Specifications:

  • Operating voltage: 6 - 8.4V
  • Power supply: 2 x 2-cell LiPo / LiFe or 2 x 5 cell NiMh packs
  • Servo voltage: battery voltage
  • Receiver voltage: battery voltage
  • Continuous current *: 2 x 10 A
  • Peak power: 2 x 18A (10 sec.) Also from an input
  • Pulse peak current: max. 120 A
  • Quiescent current per battery: 3 mA (switched on); 9µA (off)
  • Drop Out Voltage: 0,14V (at 4A total current)
  • Number of Servos: 12 + 2 separate S-Bus outputs for theoretically any number of servos
  • Dimensions: 99 x 58 x 17.5 mm
  • Weight: 135g (including switches and voltage monitor LEDs.)
  • Reverse polarity protection: All inputs / outputs are short-circuit protected reverse polarity protected and conditioned
  • - Our stated continuous current is a real determined under practical conditions continuous current! Unfortunately, there is no standardization for battery backers about how time flows, as appropriate. So manufactures will in some cases significantly higher continuous currents at this then by additions such as "Depending on the cooling air situation in the fuselage" into perspective. We regard this as the wrong way! We put also not significantly higher values of the component manufacturers are based. Our information is real time power information, which have been determined in practical tests.
  • We define the peak current by the addition (10 sec.). If we did not do that, then we could also theoretically 2 x 50 A state in which PMS Big Bus. Because this is theoretically possible when this peak current lasts only milliseconds. But this is impractical and is rejected by us.

Scope of supply:

1x PMS Big Bus 2x LED with cables for voltage monitoring 1x switch with cable (on/off) 2x receiver connection cable (JR plug system)

compatible to:

  • FrSky S-Bus
  • Futaba S-Bus / S-Bus2
  • Graupner Hott
  • Multiplex M-Link
