Shared Capabilities and Architecture
The Chroma 61500 series models share a core architecture that delivers precise single-phase AC/DC power. Both the 61502 and 61504 support AC voltage ranges of 150 V and 300 V, operating across a wide frequency spectrum from DC and 15 Hz up to 1000 Hz. They are built for demanding benchtop or rackmount integration, featuring an operating temperature range of 0 to 40 °C and drawing input power from a single-phase supply of 90 to 250 V AC (47 to 63 Hz).
For automated testing systems, both power sources are equipped with a standardized set of control interfaces, including GPIB, RS-232, and an Analog Programming Interface (APG). Local parameters and simulated wave shapes are monitored through an integrated graphic LCD display.
Power Ratings and Current Capacities
While sharing identical voltage limits, the primary differentiators between the two models are their power delivery thresholds and output current ratings:
- Chroma 61502: Delivers up to 1000 VA of AC power and 500 W of DC power. In the 150 V range, it provides a maximum RMS current of 8 A and a peak current of 48 A. In the 300 V range, it outputs up to 4 A RMS and 24 A peak.
- Chroma 61504: Delivers up to 2000 VA of AC power and 1000 W of DC power. In the 150 V range, it supports a maximum RMS current of 16 A and a peak current of 96 A. In the 300 V range, it provides 8 A RMS and 48 A peak.
Due to its higher internal capacity, the 61504 has a larger footprint, measuring 425 x 177.4 x 567 mm and weighing 30 kg, compared to the more compact 61502 which measures 425 × 133 × 503 mm and weighs 24 kg.
Frequently asked questions
- What are the line and load regulation specifications for this series?
- For the Chroma 61502, the voltage line regulation is 0.1% and the voltage load regulation is 0.2%. It maintains a total harmonic distortion (THD) of less than 0.3% at 50/60 Hz under linear load.
