Description

The DLP series is the most popular of the Dynaload line. These medium to high power units offer not only resistive loading and constant current loading, but incorporate an internal square wave modulator for pulse loading. This function allows for precise measurement of load transient response and stability. Since this function is independent of all other load ranges, a pulse signal can be added directly on any pre-established DC load level.

A calibrated current sample is provided on the front panel for monitoring current waveforms, A sync output is also provided to synchronize test equipment. External modulation inputs on the rear panel allow the user to program any DC level or waveform. DC inputs on both front and rear panels make the unit versatile in both fixed and portable applications.

Mounting ears are provided for standard rack installation. The large easy-to-read meter makes the use of external metering unnecessary. This, in conjunction with the coarse and fine load adjusts controls, makes precision loading easy. Short circuit is also provided for current measurement in a shorted condition.

Protection is provided by both current and power limits, at which point the unit simply folds into a linear limit curve. Overvoltage protection incorporates the use of a crowbar circuit across the DC input to assure the unit is not damaged by excessive Input voltage. Reverse polarity protection is also provided. Digital voltmeter and ammeter are available as an option.
