FHC Valleylab EZ Electrosurgical Generator - Electrosurgical Units - Future Health Concepts

Valleylab EZ Electrosurgical Generator (ESU)

Product Number: FHC-VALLEYLABEZ

Output Wave Forms:
Bipolar: 470 KHZ sinusoid

Monopolar Cut:
Pure: 393 KHZ sinusoid
Blend: 393 KHZ bursts of sinusoid, recurring at 27 KHZ intervals.

50% duty cycle envelope

Monopolar COAG:
Desiccation:
Low 1: 240± 40 KHZ sinusoid recurring at 39 KHZ 8% duty cycle
Low 2: 393 KHZ sinusoid
Low 3: 393 KHZ sinusoid

Fulguration:
High 1: 470 ± 40 KHZ damped sinusoidal bursts with repetition frequency of 57 KHZ
High 2: 470 ± 40 KHZ damped sinusoidal bursts with repetition frequency of 30 KHZ

Output power changes by less than 15% or 5 watts, whichever is
greater, as the line voltage varies from 90-135 volts and 186-264
volts (into a 300 OHM load)

Low Frequency Leakage (50-60 HZ)
Source current, patient leads, all outputs tied together.

Normal polarity, intact chassis ground < 10 µA

Normal polarity, ground open< 50 µA

Reverse polarity, ground open< 50 µA

Sink current, 140V applied, all inputs < 50 µA

Power Readouts

Agree with actual power into rated load to within ± 15% or 5 watts, whichever is greater. Dosage error monitor.

PER = 97

Per (power efficiency rating) is the measure of an electrosurgical generator's ability to accurately deliver the selected power into a wide range of tissue types.

Weight and Dimensions
Height: 12.7 CM (5")
Width: 40.6 CM (16")
Length: 39.5 CM (15.6")
Weight: < 6.8 KG (< 15 LBS)

Input Power Requirements
110-120 VAC 220-240 VAC
Operating Range 58-140 VAC 170-280 VAC
Max Current Cut 8A 4A
Max Current COAG 4.2A 2.1A

High Frequency Leakage
Bipolar: Less Than 60 M Arms
Monopolar: Less Than 150 M Arms

REM™ Contact Quality Monitoring System
Measurement Frequency: 80 KHZ ± 10 KHZ
Measurement Current: less than 10 µA
Acceptable Resistance Ranges:
REM™ Pad - 5-135 OHMS
Non-REM™ Pad - less than 20 OHMS acceptance range is 5-135 OHMS after Rem Polyhesive™ II return electrode is applied.

Adaptive REM™
Rem™ T rip is baseline impedance plus 40%. For example, if the
baseline impedance is 30 ohms, the upper level trip is
approximately 42 OHMS. If the pad-patient impedance falls below
the baseline impedance, a new baseline is established.
