Vitrek has launched the DL Series of test instruments for measuring digital, programmable DC loads of off-line power supplies, DC-DC converters, LED drivers, and batteries. The systems are available in 125 W, 250 W, and 500 W power ratings and support input voltages of 0-150 V or 0-500 VDC.
DL Series the platforms can support any combination of single or arbitrary loading sequences of up to 100 steps using constant voltage (CV), constant resistance (CR), constant current (CC), constant power (CW). The systems can perform current or power sweeps up to 500 steps in each direction from set values (20 µs intervals), while a voltage-dependent current loading mode supports complex variable-output power supplies. In terms of timing, the systems provide pulsed loading of up to 100 kHz.
Additional features and loading modes include:
- High-resolution touchscreen display
- Battery test modes
- Built-in scope (“scope mode”)
- Graphical X/Y plotting
- Historical data logging
- Self-test function
- Over-current protection (OCP), over-power protection (OPP), over-temperature protection (OTP), and over-voltage protection (OVP)
Vitrek claims the test systems are capable of generating high-current transient loads up to 20x higher than competitive solutions, and are also able to generate µA loads. The company also states that DL Series devices provide 2x the measurement accuracy of competing solutions at high loads, and offer an order of magnitude better precision at lower loading levels (± 0.05%).
DL Series test instruments are priced from $1,095 (125 W, 0-150 V). For more information, visit Vitrek at APEC 2020 Booth 2145 or download the DL Series datasheet.
