PDS195110. Generator w/ standard regulator. Regulators have variable amperage output- producing more amps when cold for faster charging after using the electric start. Electrical. GENERATORS. Photo`s are for reference only. Please read item title carefully. After vaporization, LPG vapor exits the vaporizer at the pressure of the liquid supply line. This pressure, either tank pressure or discharge pressure from a pump, may be too high for existing distribution pipelines and must be reduced to the system service pressure (thus, the name Service Regulator). Size and type of the service regulator is a function of pressure, flow rate, ambient temperature, and line size. AES offers service regulators from several manufacturers, i.e. Fisher and REGO, in a wide range of sizes, matched to the vaporizer or vaporizer/mixer size. Universal Voltage Regulator replaces most Onan Magneciters, old Kohler units with static exciters, and any other brush or brushless generator requiring up to 30 amps and 63 volts DC output.
