The Duty Cycle switch controls the percentage of time the output pulse is on. It also allows switching to straight DC or gated bursts of either 2 or 3 pulses. The timer reset button resets the number of seconds the output of the LR-20B has been active.<\/p>\n<div class=\"text-center\">\n<h3>Safety<\/h3>\n<\/div>\n<p>Operator safety is a primary concern in the design of Smith-Root electrofishers. Tilt sensor, water immersion sensor, and cover open sensor will automatically shutdown the electrofisher. A power output audio alarm and flashing light let all members of the collection crew know the electrofisher is active.<\/p>\n<div class=\"text-center\">\n<h3>Packframe and Suspension<\/h3>\n<\/div>\n<p>Adjustable suspension harness and packframe can be customized to fit most people. Quick release latches allow the LR-20B to be removed quickly if the operator falls or becomes injured.<\/p>\n<div class=\"text-center\">\n<h3>Compatibility<\/h3>\n<\/div>\n<p>The LR-20B uses the same electrode, cathode, and battery connectors as the LR-24 and Apex backpack electrofishers. This will increase your flexibility in large field operations and increases the versatility of your inventory of electrofishers.<\/p>\n<div class=\"text-left\">\n<h3>LR-20B Electrofisher Specifications<\/h3>\n<\/div>\n<table class=\"table\">\n<tbody>\n<tr>\n<th scope=\"row\">Output Power<\/th>\n<td>400W continuous, 39,600W peak<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Output Voltage<\/th>\n<td>50 to 990V in 11 steps (50 to 400V in 50V steps, 500V, 700V, 990V)<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Output Frequency<\/th>\n<td>10 to 120Hz in 16 steps (10 to 50Hz in 5Hz steps, 50 to 120Hz in 10Hz steps)<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Duty Cycle<\/th>\n<td>5 to 50% in 5% steps, 60 to 80% in 10% steps, Gated Burst 2 pulse, Gated Burst 3 pulse, DC<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Overload Protection<\/th>\n<td>Automatic electronic and 40A safety fuse, High output current, Output voltage out of regulation, Over temperature<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Safety Features<\/th>\n<td>Emergency shut off switch, Output active super-high brightness red LED, Output active audio alarm, Output off immersion sensor, Output off tilt sensor, High output current protection, Pole mounted output control switch, Electrode out-of-water shut down sensor, Non-conductive lightweight pack frame, Quick release harness<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Timer<\/th>\n<td>6 digit computer controlled seconds counter<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Metering<\/th>\n<td>Mean current, Peak output voltage, Average output power, Battery voltage, Battery current, Battery fuel gauge, Timer<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Battery<\/th>\n<td>Choice of 24V lithium or lead-acid batteries<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Size<\/th>\n<td>Height: 29.75 in.<br \/>\nWidth: 13.75 in.<br \/>\nDepth: 13 in.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<div dir=\"auto\">\n<div class=\"o9v6fnle cxmmr5t8 oygrvhab hcukyx3x c1et5uql ii04i59q\">\n<div dir=\"auto\">\n<div class=\"row justify-content-center\">\n<div class=\" col-md-9 col-lg-9 mb-4\">\n<div class=\"text-center\">\n<div class=\"col-sm-6\">\n<div class=\"text-center\">\n<div class=\"col-sm-6\">\n<div class=\"text-center\">\n<div class=\"col-sm-6\">\n<div class=\"text-center\">\n<div class=\"col-sm-6\">\n<div class=\"text-center\">\n<h3>Contact Information<\/h3>\n<p>Tammy Lucas<br \/>\nEmail: <a href=\"mailto:info@smith-root.com\">info@smith-root.com<\/a><br \/>\nPhone: (360) 573-0202<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The lightest weight and lowest cost backpack electrofisher (while still providing ruggedness and industry leading capabilities!).<\/p>\n<p>A benefit of the LR-20B is the simplified manual control knobs and streamlined settings that allow for rapid adjustment of output frequency, voltage, and duty cycle.
