POWAY, Calif. – Vitrek Corp. in Poway, Calif., is introducing the DL series of digital, programmable DC loads, designed to support the testing requirements for the latest generation of off-line power supplies, DC-DC converters and LED drivers.
The DL series also is equipped to handle a wide range of battery testing requirements. The devices come in three power ratings: 125, 250-,and 500-Watt versions, each with input voltages of zero to 150 or zero to 500 volts DC.
The DL series can support loading sequences that use constant voltage (CV), constant resistance (CR), constant current (CC), and constant power (CW) in any combination in single or arbitrary sequences of up to 100 steps.
The DL series provides high-current transient loading capability 20 times higher than other units in this class while also being capable of generating micro-amp loads.
Measurement accuracy typically is an order of magnitude better at lower loading levels and double that of competing devices at higher loads. The instruments allow for a current or power sweep of as many as 500 steps in each direction to and from set values and a voltage dependent current loading mode for complex variable output supplies.
Standard OCP/OPP/OTP/OVP features and battery test modes are among other loading modes also included. The instruments feature a self-test function, providing assurance that all loading and measurement circuitry is properly functioning.
Several interfaces come standard for automated use. Additional features include graphical and numerical historical data logging and graphical X/Y plotting of V vs A or W using swept loading.
