Cotek 48v 1000 Watt Pure Sine Wave Power Inverter SK1000-148
Product Description

The SK1000-148 Converts 48VDC to 110 VAC

The compact size SK Series inverters are available in 12/24/48V models from 150W to 3000W pure sine wave power inverters. The SK1500-148 offers Built-in multistage power saving functions allowing you to save your battery power when you need it most. 

Cotek offers superior quality microprocessor controlled Pure Sine Wave AC-DC power inverters for many different applications. offers PURE SINE WAVE (aka true sine wave) that provides high-end specialty users power portability for sensitive electronic equipment. The clean power delivered by a Pure Sine Wave is of the same quality and efficiency as the power provided by your utility company, which is not the case with the cheaper and more popular modified sine inverters.

We highly recommend the use of Pure Sine Wave Inverters to power Computers and related peripheral devices; i.e. printer’s, optical drives, laser copiers, and if in doubt check with the manufacturer of your equipment.

Other devices that benefit when Pure Sine Wave power is used are variable speed control motors using solid state circuitry, Audio Amplifiers, Digital Clocks and Radios, Medical Equipment, Microwaves, etc.

  • Pure sine wave output (THD < 3%)
  • Switch selectable output frequency: 50 / 60 Hz
  • Switch selectable Power Save Mode wherein the inverter shuts off non essential circuitry and reduces its no load self consumption till it sees a minimum programmed load (20 - 135 Watts)
  • Optional wired remote controls for switching and monitoring the operation. Includes Ignition Lockout and Reverse Over-ride Function (ROF)
  • Input and output are fully isolated
  • Advanced micro-controller
  • 1 load controlled cooling fan saves power consumption
  • 3 tri-color LEDs display operational status and fault indications
  • Protections: overload; short circuit; leakage; low and high DC input voltages; high temperature; reverse polarity
  • Safety: UL listed to UL-458
  • EMC: Complies with FCC Part 15(B), Class A
PLEASE NOTE: Many electrical devices require a good deal more Watts to start or energize than is required to run once started. For instance an electric motor may require only 900 watts to run but need may 2300 watts to start. Please check with the manufacturer of your equipment to obtain minimum watts for starting operation of the equipment or device. *Flat Rate shipping is for the lower 48 states only.
