Technical Specifications
Equipment Type
The Class I RF Generator is designed to work with Type CF, Defibrillator-Proof RF Devices .
The RF Generator is designed to withstand an application of an external defibrillator while
the RF Device is in use .
Electrical
The RF Generator:
• Operates from an AC Power source ranging from 100 to 240V RMS, 50 to 60 Hz.
• Includes a DIN 42801–compatible equipotential grounding lug that meets the ground bond
requirements of UL 60601–1.
Should the supplied power cord need to be replaced to match another plug configuration, the
replacement plug/cable/receptacle configuration must meet or exceed the following specifications:
100-120 VAC
- Cable: SJT16/3, IEC color code, maximum length 10 ft . (3 m)
- Plug: minimum 10 A - 125 VAC
- Unit receptacle: IEC female, minimum 10 A - 125 VAC
220-240 VAC
- Cable: H05VVF3G1 . 0 VDE, maximum length 10 ft . (3 m)
- Plug: minimum 6 A - 125 VAC
- Unit receptacle: IEC female, minimum 6 A - 125 VAC
