A measurement of the current flow. One ampere is equal to the electrical force of one Volt acting across the resistance of one Ohm.
Electricity as produced by the electrical components (utility). The unique characteristics of this form of electricity is that it reverses direction at regular intervals. For example, 120 V AC 60 Hz power reverses flow 60 times a second, hence the rating 60 Hz (cycles). In Europe is typically 50 Hz, in the USA, parts of South America and the Caribbean 60 Hz(120 volt current).
Ampere Hour (AH)
One amp of electrical current flowing for one hour.
Expresses the relationship between current (A) and time (Ohms law A = VR). AH is the measurement for battery capacity.
AGT -Advanced Generator Technology
All Fischer Panda generators, which are constructed as permanent electro-magnetic generators, are made from ceramic “Hightech” electro magnetic materials. These materials are also known as “rare earth”. Fischer Panda, especially uses the high quality material Niodym. The AGT generators are used as battery charging generators or as propulsion generators.
AGT-DDC - Direct-Direct Current
Panda AGT generator high frequency permanent electromagnetic synchronous generator (12 - 24 pole). This type of generator is especially effective. AC is transformed to DC by means of an especially effective rectifier. The aggregate is especially effective for charging batteries.
AGT-DE - Diesel Electric
This version of the AGT Generator version supplies a 3-phase output voltage (without diodes) and is used in the variable speed operation for supplying diesel-electric drives.
AGT-HD AGT Heavy Duty
The AGT-HD supplies direct voltage in the same way as the AGT-DC generators. An enhanced cooling system, external diodes and the ability to restrict maximum performance makes these generators suitable for driving DC motors (e.g. electro motors with heavy loads) over extended periods of time.
ASB-Automatic Start Booster
An electronically controlled high starting current in the control box. Suitable for all Panda asynchronous generators, to compensate the high starting current of electric motors (i.e air conditioning units etc). ASB should always be chosen if a generator is to be driven by an inductive load (electric motors, air-conditioning units etc). All generators from Panda 8000 up to Panda 14.000 are fitted, as a rule, with ASB as standard.
AGT-IDC - Indirect-Direct Current
Panda AGT Generator, which is designed like the AGTDDC to load the battery bank. In this version the rectifier is in a seperate box. these rar configuration is used if the battery bank is far away fron the generator (more then 4- 6m). The AC Power will be delivered from the generator to the rectifier which will load the battery bank.
The amount of electrical charge. The flowing current measured in amperes.
All devices that require electricity.
The very efficient power supply system is battery supported. he generator supplies direct current to charge the batteries, whilst the accumulative current is produced via an inverter. The generator runs intermittently and charges the battery, and at the same time the inverter is provided with power.
Term for DC (direct current). DC is generated by alternators and battery charging devices or Panda AGT generators with auxiliary rectifier, or DC is drawn from a battery.

Very small electrical lamp with an extremely low power consumption. It is used, in order to represent the operating systems on displays, remote control panels or other indicators.
The abbreviation used by Fischer Panda for all systems that use air-cooling (contrary to water-cooling).
Low Profile (special low style).
Term used for MTU motors.
Generator without VCS voltage regulation system.
Generator with VCS voltage regulation sytem.
A consumer attached to an inverter or generator, which requires too much current thereby overloads the device. Panda generators are internally protected against overloading.
Fischer Panda abbreviation for Perkins motors.
PM - Permanent Magnetic Synchronous Generator
A synchronous generator. An electrical field is achieved by permanent electro magnets. These generators are, as a rule, high pole version, i.e 12 to 24 poles, the frequency is 6 - 12 times higher than 2 pole standard generators of the same speed. (Frequency is 3000 rpm, 6 pole: 300 Hz, 24 pole: 1500 Hz). With this “High frequency technology” various additional components are more efficient than conventional generators. In view of the size and weight, a PM generator is up to 60 % larger and 40% lighter than a standard asynchronous generator.
The PM technology is also used for the Fischer Panda electric drive motors.

PSA - Panda Standard Asynchronous Generator
An extremely robust generator, with many positive features, that has been developed by Fischer Panda. Extremely stable temperature because of effective watercooling, self excitating because of external capacitors, diodes that do not revolve, no rotor windings, all windings are externally fitted to the stator and can therefore be cooled perfectly by means of an external cooling jacket, voltage stability by means of “VCS”, noise depression, excellent sinus curve and therefore suitable for all charging devices, closed construction gives a high level of protection. The PSA generators in conjunction with the ASB-Startbooster system supply an especially high starting current for starting electric motors (see ASB).

SC - Seawater-cooling
Direct cooling system, by which means the generator and the motor are cooled direct by seawater. Cooling of the SK cooling system is essentially more effective, since colder seawater is used to directly cool the generator.
VCS - Voltage Control System
Regulates the speed of the motor and also the generator voltage. The speed of the motor is at the lowest point of tolerance. The speed is adjusted to the highest point of tolerance as performance decreases. This enables a voltage tolerance up to ± 3 volts. Even with very high load alternation, the adjustment time amounts to less than 1.2 seconds. Voltage peaks are limited to a very short period. In the case of VCS, the frequency has a tolerance of ± 2 Hz.

As a rule, the heat exchanger is made from high quality material (copper/nickel - CuNi10Fe) (see FC).
