ANNEX II – ENERGY SAVING
“Technical Regulations on the Safety of Sea Transport Items”, approved by the RF
Government Order No. 620 of 12 August 2010, declare following in Paragraph 6:
“Designers, builders and manufacturers of sea transport and infrastructure items
shall ensure the energy efficiency of such items”.
SPEED LOG UNITS AND MODULES
Speed Log Sig.Processor and optional Sig.Distributor are using AC-supply powered
from the ship’s 230 VAC emergency power supply. The Sig.Processor and optional
Sig.Distributor are then feeding other units with internal power providing protection
against excessive voltage and interference.
Speed Log Units are developed in accordance with the following guidelines:
- Modular platform design based on re-use of proven hardware architectures
yielding stability and reliability.
- Software running under Linux and dedicated processor operating system yielding
stability and reliability during normal operation.
- Quality of selected material i.e. recognized brand name components.
The Speed Log uses low power dissipation components and is based on solid state
technology without moving parts such as rotating storage media and cooling fans. This
reduces wear and maintenance to a minimum.
POWER CONSUMPTION CALCULATION
Speed Log, power consumption (example):
1.) Speed log Sig.Processor: Power consumption 300 VA @ 230 VAC.
2.) Optional Sig.Distributor: Power consumption < 115 VA @ 230 VAC with nine
displays.
Total power supply needed: 300 VA (Sig.Processor) + 115 VA (LPU2) = 415 VA.
Recommended power supply for the mentioned example: 230 VAC, 500 VA.
