Products for oil- & gas industry
Applications

There are complex demands on the power supplies operating in the broad area of the oil and gas industries as well as marine applications. Expertise in these areas is essential where cost effectiveness has to be guaranteed. Therefore SCHAEFER represents a strategic partner who can offer solutions tailored to industry requirements. Among other things, they are designed for hermetic seal, extreme ambient temperatures and the increased noise immunity- and transmission. In addition, concepts for increased shock and vibration resistance are possible as well as special designs which can withstand extremely high pressures. Reliability is a must!

Energy supply on oil platforms, in deep waters, in pipelines, on ships or in refineries – whether on- or offshore – SCHAEFER provides durable, low-maintenance package solutions from one source.

Electrical features

By default, all devices are designed with electronic current limiting, overvoltage protection and continuous short circuit protection.

Optionally, the modules can be expanded as follows:

  • Inrush current limiting
  • Reverse polarity protection for DC input
  • Decoupling diode for redundant / parallel operation
  • Active current sharing for parallel operation
  • Hot-pluggable solutions
  • Monitoring of input and output voltage
  • Output programmable
  • Power factor correction (PFC) for single phase input
  • Temperature compensated charging voltage
  • Automatic / manual selection of charging characteristics
  • Remote ON / OFF (inhibit)
Mechanical features

By default, all modules will be offered as a 19? module or 19? sub-rack according to IP20.

Optionally, the modules can be expanded as follows:

  • Wall mount, chassis mount, DIN rail mount, 19? rack or customized design
  • Fan or liquid cooled
  • Mating connectors, wiring and monitoring instruments in accordance to the customers’ requirements
  • Digital or analog V- and A-meters
  • Monitoring & programming via potentiometer, analog signals or RS232 / IEEE488 interfaces
  • Designed for a high level of shock- and vibration
  • Tropical protection finish on all circuit boards and components to ensure an increased protection category to protect the module from extreme climatic conditions
  • Robust enclosure that can withstand wind, sun, salt water, dirt or dust.
  • Hermetically sealed enclosure for high protection category
Engineer standards

To ensure a high reliability and quality of our power supplies, they have to pass through internal testing for high industrial requirements. Furthermore, they can be tested against increased shock and vibration resistance, as well as extreme environmental conditions. All components are selected according to criteria of durability, availability and performance. According to customer requirements national and international standards can be tested in cooperation with external laboratories.

By default, the following standards are met:

  • EN 50178
  • EN 60664-1
  • EN/ IEC 61010-2-201  /  EN/ IEC 61010-1
  • EN 61000-6-2
  • EN 61000-6-4
  • EN 55011 / EN 55022 class A
  • EN 61140

Optionally, our devices can be designed to meet among other things the following standards, approvals or certifications:

  • Standards according to customer specifications
  • UL, CSA, GL, …
